One of the prominent theories on TRP is that women look for an "Alpha Fucks" to have a child and then snag a "Beta Bucks" to raise and provide for it. In that case, how can "Beta Bucks" exist anymore if their genes aren't being passed on as consistently? In fact, if we go by the 80/20 rule, it would appear that the vast majority of men are either undesirable or "beta".

Is this just a matter of Alphas suppressing their instincts and being turned into betas? Or is this a result of how our culture has developed over the years? Or something else?
