You see poverty, crime and violence in most countries.

There is no official ranking of capitalist countries, but the Heritage Foundation Index of Economic Freedom probably comes close: https://www.heritage.org/index/ranking

The top 3 countries are Singapore, Hong Kong and New Zealand. The bottom three are North Korea, Venezuela and Cuba.

I think violence is perhaps a bit more balanced; you see violence in Hong Kong and Venezuela, for example. And perhaps the crime rate is the same in North Korea and Singapore. But when it comes to poverty, it's pretty clear that you're better off in the countries at the top rather than the ones at the bottom.
