If you added a person to the world you're responsible for them. Especially if you're not putting in the day to day work of raising a kid and someone else is.
Don't want a kid? Use contraceptives. But do not blame it on the government that you now are responsible for another person. Santed a kid but realized the person you have been with isn't for you? Well then it was probably too early to get a kid with them.
Amazing. Has US individualism become so extreme, that it can't even be expected from parents to stand in for their kids, till they are grown up? Yes, metaphorically good parents would set themselves on fire to warm their kids.
If you want to support poor parents the answer isn't "fuck their kids", the answer is "let the rest of us help them".
