This is just another source showing what we have known for years --- the middle class in America is shrinking, the lower class is growing, and the difference in the proportion of wealth controlled by the upper class versus the lower class is increasing. If the trend continues, we will be like some of these third-world plutocracies in which the very few very wealthy control all the wealth and the governemnt as well, while the vast majority own nothing and work for a pitance. The key to American success has always been a strong middle class. As that goes away, so does the strength of this nation, and its stability.
