I think it's actually pretty true. No matter how hard you want to believe otherwise.
Societal pressures and moral value have assuaged the standpoint a bit from purely caveman logic but the core values are the same.
You can bitch all you want about how you're a deep person and that you'd never date someone so shallow and stuff, but to be brutally honest (and to paraphrase Ladder Theory) there doesn't exist a couple in the world where the woman didn't wish her man had a bit more money and the man didn't wish his woman's body was a bit nicer.
If you're ugly and broke then, relative to the mean, you will never get very far.
Personality comes second to looks and money.
If you disagree, you are either masking the basic truth and are in denial, wrong or both.
