Based on my personal experience (DW, mom, sister, sister-in-law, mother-in-law) women in general prefer to do something they enjoy or something that brings them satisfaction. Men on the other hand don't care much as long as it makes money.
Sure, I enjoy working with computers but if it didn't pay well I'd probably be doing something else. In fact, I keep telling my wife I don't mind quitting my job to start a business of some sort as long as it would make more money. She always asks me questions like "you're willing to give up something you've loved since you were a kid, something you've invested so many of your years in ?" - my answer's usually "sure...as long as my new profession makes us rich".
I'm sure there are many women that also think the same way and many men that think the opposite but I think we're talking about the majority.
However, on the topic of men vs women, one thing that I'm convinced of is that men suffer from genetic mis-programming. Almost all worst offenses and crimes are conducted by men
Serial killers, rapists etc - I wish there was a way to identify people with such flaws at birth using DNA or something...
