Everyone else is (rightly) shooting on you for hating poor people. And there is some validity to what you're saying about some portion of the poor adults you're talking about. So the question you should be looking at is, "How do I get there to be less poor people?" Sure you could suggest a modest proposal, or you could promote ideas to minimize those poor children growing up to be poor adults. So what things make poor kids grow up to be poor adults? Well, the three biggest you're going to see are lack of education, poor health and nutrition, and poor housing security. If you look at the numbers for anywhere else in the world, you'll see that unless you're fabulously wealthy you will generally see better health outcomes from universal healthcare, and it will probably cost you less, too. Properly funding public education is another key factor in making sure those poor kids have every chance to not be poor adults. Whiles you're at it, keep funding those school lunch programs. Don't worry, for every dollar spent on those, the economy sees multiple dollars of improvement. Housing can get a bit expensive, and even if you just did those other two, you would be doing a lot to reduce the number of poor kids who grow up to be poor adults. Now, if you were so outrageous as to propose police reforms to the point where the kids are less afraid of the cops than they are of the local gangs, that might be a benefit, too. Granted, none of this is quick or easy.

When it comes down to it, poor people are always going to cost something to deal with. You can worry about health, education, housing and social assistance, or you can worry about policing, jail, and supports and corrections for children. Neither option is free.
