Poor people care about their kids, too. They're just struggling to keep a roof over their heads and food on their plates instead of worrying about what college their kids are going to get into.
Assuming we're talking about the US, this is just not true. If you are actually poor, then the government has incredibly generous programs to put food and shelter over your head. Where I live, the city government will literally paid for your daycare and you can enroll in lotteries to buy homes at 1/10th the regular price.
