The global south is largely a terrible place because of the wealthy north. Especially the US. First they had to throw off their colonizers. Then they had to suffer the punishments of their former colonizers. Then the US took it upon themselves to attempt to overthrow every socialist leading government in the western hemisphere, elected or not, and replace them with a dictator. Then in the Western Hemisphere the US War on Drugs have made Mexico, Central, and South America a war zone run by cartels.
So yeah, much of the world is much worse to live in than the US. Mostly because of the US. Western Europe is still a far better place to live.
