This is insane. Looking at the graph one can see that the last time it was this bad was in 1928 - before the depression and Roosevelt's regulatory laws. Roosevelt's laws protected the people and let the average person have an opportunity.
All went well until Ronald Reagan got elected, and took away all regulations for big businesses. The people let him do it - it was the '80's and being a "Material Girl" was in fashion.
Greed was promoted. With greed one can destroy families and destroy society. One does not have to be rich or an Elitist in order to be greedy.
Each one of us has the responsibility not to let greed take over our lives. That is the first step to a more equal and sustainable society.
