For whatever reason, the vast majority of golddiggers are utterly dishonest about what they are really seeking. This leads men to get into bad relationships (which they would have avoided if the woman were honest), and they often lose big when their career doesn't turn out the way they hoped or when they want to downsize their job (e.g., quit the $300k/year corporate law job for an $85k/year public defender job).
I've got no problem with that rare girl who openly admits her desire to trade sex for money. I don't want a relationship with her, but I won't condemn her.
[edit: I'll similarly condemn a guy who lies to honest women to get them into bed. I'll giggle when a guy lies about money to sleep with dishonest golddiggers.]
