"Anyone who thinks there are obscenely poor people in the United States need to take a trip to Africa."
You need to get out more. Try going to the neighborhoods that people say you should stay away from. Or spend a day with some homeless people.
"I don't believe there is such a thing as obscenely rich, unless riches were gained through theft or government handouts."
Funny you should mention theft and handouts. Those two things have gone a long way towards making or keeping people rich in the US.
