First question -- I've always heard that " married men make more money because they have the motivation to provide for a wife and kids " But is this really one of those things of cause isn't causation ? Is it more likely that men who make more money are more strongly pursued by women who want to get them as a husband? In other words, the man isn't making more money because he's in a married situation, he already had good income potential and the women chased him into marriage?

Second question - is it a dirty unspoken secret of society that -- all other things being equal -- single/bachelor men can have better income potential than married men because they don't have a wife and kids to divert their focus? And society just doesn't want to admit this?
