This video came out two or three years ago, but it's telling on so many levels that it is worth looking at more than once. The reality is that it may be even more pertinent three years later. The mere “tweaking” of the system will not change anything.
Wealth Inequality in America

It is in the short-term interest of the plutocracy (read globally) to keep it this way.
