Is it ALL under capitalism? The 20th century was an on-going battle to see what political system would take over, and capitalism took the lead, but it's NOT because it took over, but rather that the other systems collapsed under their own incompetence. Long story short, capitalism is the only known system that has at least produced some wealth, granted in the process also produced greater inequality, but again, I'm not convinced those problems are entirely due to capitalism, and it could well be the case that more wealth will always produce inequality until we find a new complementary system that doesn't attempt to undo capitalism and instead works alongside it.
