That's Darwinism in a nutshell. It's a mistake to think that "unfit" (a vague, undefined term that totally depends on the species and circumstances as it is) means "will always die before breeding". The idea is that the "unfit" are supposed to be the oddballs in a healthy population.

But gee, what happens when all the selective pressures shut off, and the "unfit" are allowed to proliferate?

With the population explosion not selecting for quality, you'll eventually wind up with not old people burdening society, but with too many retards who can't even wipe their own bums, let alone maintain a high-tech, civilized society taking up too many capable people who are now too busy wiping the retards' bums to do anything useful.
