I think "self-anointed do-gooder" captures the idea perfectly. Many of these folks want to help Africans and many low-income countries, but arguments on Hacker News and government decrees don't help the poor.

Only free trade, preferably between rich and poor countries, can lift the poor out of poverty. Initially, it starts in a way you might consider "unfair" but soon, that unskilled labor learns better skills and starts to negotiate better wages.

So, like I said, many of these "do-gooders" sincerely want to help Africans but their approach hurts even more.
