Parts of the US = Third World

[Sander]

No. Once you start using "class" to describe the U.S. you've already failed. The society is incredibly fluid. People move here from Guatemala or Laos with nothing, work as housekeepers or in a factory, maybe open a business, and their children end up going to Stanford or Harvard. It happens all the time. The parts of the country that are perpetually backward are that way because of culture, not class. In short, if you're good at something, you succeed.

Class is just a useful shorthand. Replace with income level and my point remains valid: people with very low income have it real shitty in the US.

Class also doesn't mean there isn't any income mobility. I have no idea why you're reading that into my statements.
