Back in the day, stupid people would naturally remove themselves from the gene pool. Being stupid HURT and was a likely death sentence.
Now we bubble-wrapped the world and put warnings on everything. We limit everyone’s freedom to prevent stupid people from hurting themselves. We feed and control diets of people too stupid to feed themselves. We feed the children of idiots, nomatter how many they breed.
Under such conditions, the amount of idiots will naturally increase exponentially every year until there aren't enough competent people to take care of them.
Compassionate, yes. But it's no different than being compassionate to a group of feral dogs in your home and letting them breed. Eventually they'll take over your home and everyone dies...horribly.
