I would argue that there are few, if any, countries in the world that this description would not apply to.
However, I agree with the point that you're making wholeheartedly. There's a very serious amount of wealth disparity around the world, and the rich have gotten so rich that they can't even feasibly spend all of their money if they had to.
The lives of middle and lower class people in Australia, Canada, Scandinavia, etc. are much, much, much better than Americans, and improving all the time.
Do you think so? I live in Toronto and wealth inequality is still constantly at the forefront of political discourse. Obviously Toronto isn't indicative of the rest of Canada, but I don't feel as if poor Canadians are especially better off than poor Americans.
