Notes on the numbers.
The distribution of annual produced wealth in America in 1980 was 50% to below the median income (which was about $30,000 at that time) and 50% to above the median income.
As a result of 30 years of Reaganomics, the distribution is now 10% to below the median and 90% above the median.
This is a profile of a neo-feudal economy, not quite where Europe was before Restoration. If you need a picture of class warfare, behold.
