The Roaring 20s versus Today regarding the stock markets

 I found this graph today online. I'm not sure if it means anything at all. One thing I do know, however, is the ratio of rich to poor is about the same as during the same period from 1921 until 1929 from  2009 until 2016.

My thought is that if there are too few rich and too many poor (comparatively speaking) that the poor have less and less motivations in supporting the rich stay rich. This is why we are the best here in the U.S. when we have a healthy middle Class which we had until the 1980s and 1990s from the `9. Our middle Class was caused mostly by having Unions championing workers from the 1930s until Reagan busted up the unions during the 1980s. So, the death of the middle Class came from Reagan, Clinton, Bush and also to some degree Obama too.  Because of this a crash wouldn't be stopped by the poor who have no vested interest in helping the rich the rich unless they get their slice of the pie too. So, without Unions (or something similar evening out wealth more here in the U.S.we likely are headed eventually for something worse than the Great Depression eventually worldwide.
