The success of the United States economy was almost entirely built on slave labor. Dubai and Qatar, some of the most economically successful countries in their region, are essentially entirely built on slave labor. It is making a comeback in the US because of how efficient it is in the form of mass incarceration combined with prison labor. The inference 'economic success' -> 'morally good' is, well, horrifying. Slavery is a good counterexample but old since it's so abhorrent countries have mostly abolished it. Sweatshops are another good example.
Exactly, you've clearly stated my original point -- economic success in countries has nothing to do with the morality of their society or culture or government. Economic success is more often than not luck of the draw and can happen to brutal slave dictatorships as much as free market democracies.
