when you look around the world and start thinking about it, you realize disparity is a problem.
Where is the problem? I see countries like China and India bringing hundreds millions of people out of absolute poverty, yet they also are seeing income disparity widen.
Indeed, income disparity was less in China when Mao starved 20 million people to death in the Great Leap Forward and persecuted millions during the Cultural Revolution.
Because the original money is hoarded by the wealthy.
Every rich person I know has invested their money in productive capital. Heck, I have a few hundred K myself invested in capital stock. Even cash money in the bank is used to loan out to others.
