This has 2 issues about it: Children of poor families, and drawing a line somewhere for those being assisted by gov't.
I agree about people who can't support them shouldn't be having kids. I agree with the underlying concept of curtailing unreasonably stupid people from diluting the gene pool. Obviously if it's a gross state of what Evil Q said, something ought ot be done to discourage it. Something ought to be done to discourage future occurrences.
Having said that: before cutting funds, maybe a look into why a family is poor, first? Couldn't hurt. Begin the transition NOW. As to those already existing on gov't. aide, assist those for the time being at least.
That's right, Bixby Snyder folks.
