ah..I see mr "money is EVERYTHING" has joined the conversation 
Is it everything? No. But its a big factor. You can take 2 equally good looking guys with similar personalities. One guy makes 500K a year, the one makes 50K a year. Who do you think the woman will go for?
From an evolutionary perspective, they would take the 500K man a year.
Obviously, if you date trashy women, then it wont matter how much you make. But for many professional, highly educated women, salary/occupation is a big thing. There are exceptions to the rule, of course.
But keep telling yourself it doesnt matter if it makes you sleep better at night. Hey, man, whatever keeps you going, ya know.
