How is not wanting to date an unemployed man any different than men not wanting to date a fat woman?

I used to be depressed and fat. I lost a lot of weight and suddenly many men want to date me when they didn't before. Should I be bitter and say " you didn't look at me when I was fat so why should I care about you now" ?

This is how the "women didn't want to date me back when I was nothing so now I don't take them seriously" sounds. What's so bad about women wanting a man with stable finances? (especially if these women want to have kids somedays)
