Now that the individual's economic future is so uncertain, and it's that way for everyone, people who don't think about the future are breeding at a much faster rate than people who do, and it's terrifying.
For the life of me, I can't figure out why healthcare (which has long-term effects on peoples' intelligence levels, since a lot of that's not genetic) isn't a no-brainer, but also education. Free higher education is the absolute best eugenic program ever devised-- if your kids are smart, society will invest limitless resources in making them succeed-- because it hurts absolutely no one; it's pure carrot. Instead of getting soaked on tuition, parents whose kids get into top schools should get paid.
