It might not be the world we want to live in, but that's life. Natural selection is the name of the game.
It baffles me that people think social development can be somehow exempted from evolutionary processes. Call it callous or compassionless, if you want, but there will always be less fit members of a species/society. Humans didn't get to this spot on the food chain by subsidizing failure. If we want to increase prosperity, we should stop encouraging the propagation of actions/ideas/genes that would otherwise be unsustainable without throwing short-sighted policy and/or tax money at it.
