The root problem is that we people of the Global North are incapable of looking ourselves in the mirror. The obvious solution is to stop all of the frankly idiotic overconsumption that hasn't increased our well-being in decades and – when no overconsumption means no economic growth – rebuild our economy on equity, instead of feverishly insisting that accumulation of almost all of the wealth to a few people is a the only alternative.
