I agree. I believe reducing wealth inequality is the best path towards stable global population. Nearly half of the countries in the world are already below the population replacement rate - and it seems birth rates are inversely correlated with wealth to some extent.

If we can end war and poverty (and that's a pretty big 'if'), I think global population would stabilize and this would be a non-issue.
