I'm happy to be married with a girl I met while I was still a pauper at Uni, who has gone through thick and thin with me since, but to be honest I still believe that the way most girls are fundamentally wired is to find a partner who either is already successful, or at least whose entire nature shouts that he has the promise of success in his future.
It's a character feature developed from biological influences after centuries of role modeling, a woman will seek out that partner who is most able to provide for her children.
It's sort of like men saying they look for a woman with character etc, but at the end of the day good looks certainly don't harm any girls chances of "mating", just like most girls would never admit that subconsciously or consciously they go looking for winners with whom to partner.
There's always the odd exception to the rule, but on the whole successful men with the aura and self-confidence that both begets and results from success have better and more chances of anything from one night stands to getting a good partner for life, while the same holds true for attractive women.
That I think is where some guys go wrong, if you have enough money to buy a sports car but are otherwise a loser the car alone won't get you free sex, whereas if you're a winner who hasn't made his pile yet you will be having fun.
