And this is why Sweden has a more creative economy than the US. The state takes a bit more from the rich so that those at the bottom have at least, decent housing, health care, nutrition and education.
In a capitalist system the top 10% will always be richer and the bottom 10% will always struggle. And this would still be true even if a magic genie came a long and made everyone ten times smarter.
This isn't a knock on capitalism. Capitalism scales where many other systems don't. (I'm looking at you communism.)
