Western Civilization depends on western children. I'm pretty sure we're all in favour of either keeping, or improving the civilization we have.

Yes it does. Idiocracy is a far-future documentary, not a comedy. We absolutely need to encourage the highly intelligent to breed.

>It doesn't depend on high-consuming Westerners having children tho'.

Right, because everyone else wasn't going to burn oil and coal? It takes an advanced society to produce energy responsibly.

Also if we never leave earth we will die, so yes you do need humans to continue getting more intelligent. People with below-average IQ's breeding are just contributing to the problem.
