I don't know of any women like that. I have a post graduate degree and work, I have a lot if female coworkers many but not all of which have kids... They all enjoy having a career.

That sounds like a male stereotype for a gold digger, I wouldn't buy into that being the norm. Nowadays women outpace men in getting college degrees and almost outpace men in terms of % employed. What few stay at home moms I know made the choice because their salary wasn't much more or was less, than the cost of daycare which can be 1k plus per child. Of those women I've seen most go back to work once their kids reach school age.
