it's similar with governments actually: All the talk about human rights, social justice etc. are usually way less important to the government than the GDP and hence capitalism/profits. BUT, this is not only good for the top x% but good for everyone usually. With profitable businesses you can pay everyone and everyone is getting richer, thus everyone wins. At least unless the top x% keep the riches to themselves, that's when the government should intervene. If they don't, it's up to the voters. So the system has quite a few fail safes. (although I agree it's not enough nowadays, especially regarding those oligopolies and climate change.)
