Some women use it as a threat when their boyfriends attempt to break up with them while they're pregnant or have had the child. It is nothing as another woman, I see it as a threat to men to make them stay until the child is 18, even if they're miserable. It is also a minor-discrimination against men. If a man knocks a woman up and he doesn't want to raise the child, it should be his choice and not hers. She shouldn't make him stay at all. Child support takes about 85% of a man's income and leaves him with a minuscule amount of money that is not even enough for a human to live efficiently. If anything, don't let the man have to give anything to the woman, let the government pay her. This would work good with single mothers.
