The Man Tax!

Are you a utilitarian? If so, then you should support the man tax:

Spain’s Popular Party has proposed that women receive tax breaks for… being women! Since parties to its left are likely to pile on board, Spain will soon have a tax system that discriminates on the basis of gender. There’s a radical feminist argument for this, but there’s also a utilitarian argument based on the Ramsey taxation principle: If the demand or supply of something is more elastic, tax it less. Since women’s labor has greater elasticity than men’s, it should be taxed less. This seems to reflect a profound tension between utilitarianism and equality.

For some reason, I don't much care for the idea myself...
