Go out on any street in America, you will see couples who are overweight, couples who are low-income, couples who are uneducated, physically undesirable couples. All you need to do is go out to any neighborhood in middle America and you will see people who do not have their lives in order by any measure in relationships and married. Go to Comic-Con and you will see unkempt cosplaying couples. Most men eventually end up being paired off in their twenties. Acting as if lifelong loneliness and celibacy is some typical never-ending condition that the average man just has to accept is delusional. Now the bar may be higher depending on the type of woman being pursued of course. Poor, out of shape, or nerdy women are not only holding out for top tier men. There are enough "low-value" (In this sub's words) women for undesirable men, unless they have very high standards. If a man cannot get a relationship or remains celibate by the time, he is well into his twenties, despite actively trying, he is seriously doing something wrong. Either he possesses a very off-putting personality or is tragically aiming above what he could feasibly get. I cannot think of anything else, given so much of America is completely average and mediocre, live dead-end lives, and still are able to pair up and raise families.

My argument is that the bar for men is low enough that they could get someone if they really wanted, since most men succeed. Time to introspect!

Edit: Tired of all the men here blaming women. Improve yourself.
