I recently came across a statistic of the most gender egalitarian countries in the world , in part thanks to Bernie Sanders for referencing the Scandinavian countries, but also thanks to a follower who was kind enough to link it to me in a direct message on twitter. Several authors in the sphere have drawn inferences from the advent of feminism towards a decline in the rights of fathers, and towards the emergence cuckoldry as the norm, as the reductio ad absurdum result of feminine sexual strategy becoming dominant .
In the upcoming Gendernomics book, I reference a study that shows that 8000 years ago, 17 women reproduced for every 1 man, something that points towards the existence of a situation wherein a small number of men did all of the reproduction with multiple women, while the remainder of men had no chance to reproduce . This is perhaps a manifestation of the two optimal reproductive strategies overlapping, for women it would have been better for them to share a single high status man that gave them access to both high quality genetics and material affluence to ensure the survival of the woman and her children. For men, the sexual structure that ensures paternity, and gives the most possible offspring is polygamy, the monopolization by one man of the reproductive capabilities of multiple females.
What gives females the optimal situation in which to reproduce and raise children, is the assurance that they have optimized their sexual strategy in such a manner that it secured for them, both the high quality genetic material from the Alpha male, a man who exhibits those traits that ensures his reproductive success. Secondly, the assurance that this will not cause her or her children to suffer for a lack of resources. One can argue the securing of alpha genetics by a female as extreme long-term strategy, as her choice of genetics is what determines whether or not her lineage becomes successful. The securing of resources is a short-term strategy, as this seeks to ensure security and prosperity for the next 20 – 30 years until the children are able to take care of themselves.
One must keep in mind that resources are a present problem, that can lead to imminent death, yet if offspring are poorly suited for survival, in a situation with scarce resources, it follows that perhaps a better investment is to attempt to breed better children, or children with higher genetic variety.
Single-Parenting an Economics Perspective
One of the first statistics I came across as I was researching the topic was that single-parenthood, even within the Scandinavian welfare states leads to economic hardship, as the statistic demonstrates that single parents with children have the least disposable income of any class within the societies .
This mirrors the United States  and The United Kingdom , which supports that being a single-parent is not a good financial decision. This is further supported by EUROSTAT that stated that in 2014, almost 50% of all single parents were at risk for poverty. However, an interesting study showed that while about 4.2 million single-mothers live below the poverty line, only about 400.000 single-fathers are living under such conditions . Furthermore, the study outlined that single-mothers who were divorced were less likely to be living in poverty than those who had children and subsequently divorced.
The child allowance given from the state to single-parents within the Scandinavian states show an interesting difference in that Sweden does not increase it for single-parent households, which is reflected in that Swedish single-parents also have the lowest disposable income out of the 5 countries in the study.
An interesting characteristic is the relatively high amount of single-parent families within the Nordics , which is a comment made, but which shows no reference to the number. There were some numbers available, in Denmark for 2007, roughly 19% of homes were single parent homes and about 20% for Sweden, the other countries were not featured. 
Fatherhood in the Most Gender Egalitarian Countries
The major issue with the statistics referred to in the previous section, is that they do not distinguish between biological parents and those who have decided against better judgment to cohabit with a single mother. Combined with the fact that a common manosphere observation being that women frequently divorce or leave their alpha genetic mate, and elect to then build a new house with a beta male, only to leave their beta to shack up with an alpha or a better beta, or various variations thereof. Thus, the statistics cannot provide a full explanatory framework or serve to prove the manosphere assertions fully.
However, an interesting observation from Norway is that a quarter of of men never father children, similar statistics were not found for Denmark and Sweden, but for the United States about 87% of women reproduce and 82% of men. An interesting quote from the researcher who conducted the study was:
“But women are always the pillars of a society’s fertility.Norway can, in other words, be a country where many men never father children, even though its fertility rate is high. Most men and women consider children to be an essential element of their lives. Few make a conscious decision against having them. What actually happens often is that men who are already fathers get recycled.” [12, 16]
What is this if not a form of sequential harem, where a male has children with one woman at a time, but trades the woman in for a new model in cycles. Another comment on the same results from the researcher was:
“According to the first theory, men with little or no education are disregarded by well-educated working women. Rather, they “recycle” well-educated men who become fathers to more than one brood whereas less educated men are not taken into consideration and miss the opportunity to become fathers. ” 
The second theory, is that men voluntarily opt out, something which appears contradictory given the psychology today article that outlines a desire to become fathers among men .
In an effort to confirm these statistics I elected to access the Office of National Statistics in the United Kingdom, however after an exhaustive search, it appears that the study cited above is unique, in that most countries only measure childlessness for women, this was found to be true for Sweden and Denmark as well.
Statistics of women who remain childless are plentiful, and demonstrate that it is quite a common state for women. Unfortunately, the equivalent statistics for men are difficult to come by.
A Psychology Today article outlined that among more traditional tribal groups, the majority of men do become fathers, however those who remain childless are those men who have not yet attained enough status or resources to be a good prospect for marriage.
The author outlines that in societies that practice serial monogamy and polygynous societies men experience more reproductive variance as opposed to when men are in strictly monogamous societies. From a gendernomics perspective, I’ve titled them in reverse order as “Reproductive communism”, “Reproductive Oligopoly” and “Reproductive Mixed Market“. 
The results of these studies are consistent with the manosphere theory that as women gain more control over reproduction and thus can enact their sexual strategy to a larger degree, it trends more towards a female preference to share one high status male, over having a lower status male all to themselves.
One must consider that a male with two or more sets of offspring, will in most cases with modern child support laws have to share his resources between multiple women and their offspring. While this is not quite the same as polygamy, it mimics some of the mechanisms.
A major factor here could be that as the welfare state acts to reduce the wealth gap between exes, in practice making men worse off and women better off .
This contributes to reduce the risk and consequences of sharing one male among multiple females, by utilizing those single males to finance the feast over the tax-code. The question is, if laws such as the recently suggested Swedish law that would permit fathers the same rights as women, namely legal abortion up until the end of the first trimester , would this even affect the situation? Men who opt out of fatherhood would merely be taxed rather than make child support payments.
Summary and Conclusions
As the statistics show in the example of the Nordic countries, as a country becomes more egalitarian, this affects divorce rates, single parent households and female choice.
The recycling of men into second and third groups of children with different women, something that has also become a trend in the United States where up to 28% of women have children by more than one man, in a form of reproductive mixed market, is perhaps facilitated more through the generous Nordic Welfare states. [18, 19]
A researcher states in a Jezebel article
“And Dorius herself went even further, saying that multipartner fertility isn’t just a byproduct of inequality, but an engine of it: “Juggling all the different needs and demands of fathers in at least two households, four or more pairs of grandparents, and two or more children creates a huge set of chronic stressors that families have to deal with for decades.”” 
Many such stressors are perhaps alleviated through the welfare state providing health, financial assistance, and many other forms of assistance especially aimed towards bettering the situation of single mothers [9, 11]. In effect removing the consequences of women engaging in much less covert versions of cuckholding, branch swinging and all out hypergamy, the growth of the single mother phenomenon  with the consequences of to the children [22, 23] are quite scary.
However, looking at the countries that have gone the furthers in not only enabling, but in many cases rewarding women for becoming single-mothers, one must wonder if the manosphere assertion that the welfare state grows from the needs of women is accurate. After all, if given a choice where she suffers few financial consequences, there is no social pressure, and there is no religious pressure, but removes accountability from her life, what is the incentive to raise children together?
The manosphere views of the mating competition and how it works if the historical constraints on female fertility are removed, are largely validated by the data sets that were explored in the context of this article. With a welfare state to cover the role of provider, a strong and stable state to cover the role of protector, women are free to act in accordance with their wishes, and their wishes match very closely with the manosphere concepts of hypergamy, solipsism and branch swinging.
There are countless programs to assist single mothers in every modern industrialized nation, however the nordic states have taken it further by aiming to equalize incomes between not only prior spouses, but between working and non-workering parents. Therefore, one must wonder if the slide towards Open Cuckoldry as outlined by Rollo Tomassi as the logical end-point of female hypergamy  is merely a function of social development that removes the natural constraints placed on women from a biological perspective.
This state of reproductive oligopoly is proven not to be an invention by men to hoard female fertility, but a result of female biological preference and thus what is the natural end result when the human female is granted all rights but no accountability.
