Because as long as we have capitalism it will be the poor and minorities that will be restricted from reproduction. The US had had its fair share of eugenics in its history [1], and the Nazis have shown the worst examples by far.
Besides, it is not even necessary to delve into the questionable ethics and side effects of eugenics, forced sterilizations, one-child policies and similar ideas that have been tried and proven catastrophic when the Earth has way more than enough resources to feed all the humans on it, even in Africa. The problem is that we manage the resources we have completely wrong:
- the US has utterly absurd and wasteful grandfathered water and other natural resource rights, and obviously companies exploit them simply because they can and because Nestle in particular has spent a lot of money on lobbying to ensure they can continue leeching off of society [2].
- an absurd amount of food (depending on estimation, 30-50%!) goes to waste due to spoilage, because it doesn't meet quality standards (the running joke in the European Union was a directive that limited cucumbers from being too curved [3]) or because it is discarded in restaurants due to oversized portions
- some countries commit crimes against nature, e.g. Brazil burning off the Amazon forest to feed cows that end up in the US and EU, and governments allow this atrocity instead of banning meat imports from there
- agricultural land is abused for drug production (cocaine in South America, poppy in Afghanistan) because drugs are worth so much more money to cartels than farming to feed the population could ever be
- Africa in particular has lost a lot of its agricultural power due to political mismanagement and toxic donations from Europe and the US (it's hard for local farmers and textile producers to compete against virtually free handouts)
- European and US agriculture subsidies have completely warped into a monstrosity that favors large ultra-farms over small operators
love to see HN brain in full effect, where someone gives the correct analysis, but because it runs against the HN libertarian groupthink, it gets downvoted
