Liking someone for money is like liking them for their personality. It takes effort to acquire a lot of money and that can be a testament to their work ethic, intelligence, etc. It's not always about materialism.
No, the money may not be there forever, but where did people get the idea that personality always stays? People can change, too, or be unable to manage mental illness.
A man can accumulate wealth, but a woman can't accumulate beauty. You either got it or you don't. Unless youre a polished poop. Then you look hot after two hours in the mirror but like shit fresh out the shower.
