Not much of a post, but more a comment. The current economic policies and trends are totally destroying the middle class. While the upper/rich class may be the “brain” and the lower/poor class the “body” and “muscles” of society, the middle class is the “lungs” and “heart”. Mobility will never stop. Peoples will move up and down the social strata. But what is going to happen is that less people will move up and more people will move down – all the way down. The middle class is like a midway house that allows recovery.
BTW, if you were wondering, I am a staunch capitalist, thus I fully support the middle class.
