Men can't do housework?

Big paycheck means less housework for married women

Let me see if I get this straight: women who earn more money do less housework and that's bad.
But men who earn more money do less housework and that's okay?
You know, there are two people in a relationship. Women should not be the partner responsible for the housework. The man who lives in the house is just as responsible for it's maintenance.
This study is utter tripe.
