If I have 100 people who are making 10% more than the level necessary to live comfortably, what do they do with the leftover capital? Do they save it? Do they invest it? Do they buy more stuff in an attempt to increase their standard of living?
Do you understand the difference between 10% more than the level necessary to live comfortably and those who possess more wealth than their children's children's children will be able to spend?
"Trust me, the billionaires can spare it. The total wealth of the average American family is $57,000. Convert that into hundred-dollar bills, and it’s a stack about 2 inches tall.
"The one-percenters, at an income of around $300,000 a year, earn a stack every year that's about a foot high.
"But the average wealth of the billionaires on the Forbes 400 list is $4.2 billion. Convert that into a stack of hundred-dollar bills and it would reach over two miles into the sky. It would be a navigation risk to aircraft."
