This is a graph of the income of the top ten percent of of the population showing what share of total income they get their hands on. There is a startling correlation between the two graphs which indicates that a shift of society's wealth is related to an increase in private debt: I. e. The rich get richer at the expense of the rest, to a point where the bubble bursts, and then the process starts all over again. We are now nosediving into a similar situation to that of the 1930ies, as indicated by the graphs.
