Hypergamy

An evolutionary psychology theory that beta males and feminists refuse to look at or even acknowledge exists. They will usually blame the MGTOW and MRA community for making it up, but that just shows their lack of research, even though these same groups will tell their detractors and opponents to "do your own research" or "educate yourself". The theory itself is the study that women seek higher status men and men with more resources to give her seed to the best possible mate. There is nothing inherently wrong with this, but left unchecked can cause societal problems.
