What you're saying definitely makes sense, but I would argue that the large amounts of average and below average people are the result of entertainment, phones, porn, lack of exercise, fast food etc. I'm not saying that the problem could easily be solved, however, I'm quite sure that if porn weren't so easily accessible and schools and universities made students follow a daily exercise regimen of bodyweight squats, lunges pushups and pullups, that would already significantly reduce the amount of fat and lazy men/boys.I'm sad to say that in this world the good of having so may humans born strains ecology or induces more evil leaders to (over time) try to cull the herd. It takes a long time to get there, but I've been trying to make this point of the board for over a year now. High numbers of men in safety and without war for a long time (medical innovation, no real plagues, no real famines) is ultimately an ecological disaster if you want higher quality women. It is a complicated situation due to the loss of religion in the west over that time as well, but that is also what happens when you get increasing numbers of (absolute numbers) of average and below average people. I know this sounds like an elitist position but it's actually, quite clearly the case. Let me prove it another way - what's the strategy for increasing numbers of men that have trouble competing with other men? Things like lying to women and feminism, white knighting politically, etc.
Even most of the self improvement industry at its core is really just saying: "go outside, exercise, read, stop watching porn." That alone is already life changing for many people. The fact that they need someone to actively tell them to do those things shows that there is something very unnatural about the way humans live right now.
