I encourage you to watch the 6 minute video completely and keep an open mind.
I do understand this topic has been discussed thoroughly already, but I think it is interesting how it samples the perception of the issue by the American people.
Wealth Inequality in America - YouTube
Samples on whose perception?
Socialists will always call for wealth redistribution, cry about one-percenters, fairness etc. You know what? I don't give a shit for their moral values, just like they don't give any for mine. They cry about greedy rich just cause they're jealous. They would do the same if they were in their shoes.
Just because rich are having more, doesn't means that poor are having less. What liberals are not getting is that wealth is not zero sum game. That video in OP shows wealth as limited amount of money where if one have more, the other automatically have less. Our physical resources may be finite, but wealth is not. Why? Because physical resources can be arranged and re-arranged over and over in many patterns, with each iteration creating more wealth using the same amount of resources. Some are just better in arranging patterns game then the others. There are 210 new billionaires this year. How they got all that wealth? No, it doesn't mean that everyone else has lost billions in order for those new 210 to have it. Some people created billions pretty much out of thin air. Take Google or Facebook or Amazon, their wealth came from idea, knowledge and taking the risk. That's much different then creating money out of thin air, as Federal Reserve does, but that is another story.
Our problem are not rich people. To make it simple, roots of our problems are corrupt politicians, lobbyists and debt.
