That's only in theory but it's not true at ALL.
I don't know what world you live in but in black communities it's quite obvious that holds no water.
I think men try to convince themselves that looks don't matter because they don't wanna be judged based on their looks the way that women are. It's too much for them to bear, so they lie to themselves and say the only thing that matters is confidence and swag or whatever you wanna call it.
Attractive people have more advantages, period. I don't be seeing these tall attractive nikkas who are broke. I think they're a figment of some people's imaginations.
Research has shown that there's strong correlation between attractiveness and income. There's no reason to believe that things are different in the black community

A lot of dudes just need to feel secure thinking that they have what women want but the fact is the majority of men don't and probably never will be a woman's first choice.
