What's really scary about the wealth distribution shown in that video...
...is not just how bad it is, but how much worse its gotten in just the last few years. The unequal and unfair distribution of wealth seems to be strongly correlated with the general health of the economy. That is, the poorer the country gets, the richer (and smaller) the moneyed elite gets. This was not normally the case in the USA, it is the kind of wealth distribution you expect to find in places like ancient Rome, Imperial China, or 18th Century France. America is starting to turn into another India.
I realize correlation is not necessarily causation, but sometimes you do find a trout in the milk.
