As an adoptive parent of two kids from foster care, I know this is biased. And actually now that I’ve got a few years of parenting kids with trauma under my belt I actually think most people shouldn't take on this challenge, because they actually wouldn’t be able to handle it. That said, I think that’s the only real way to counter the idiocracy effect. Adopt kids of the least responsible people to those who are most responsible. It’s mostly an opt-in, self selecting process that generally only moves things in the right direction. It’s also not really enough to actually offset the problem as a whole.
