The Haves vs The Have Nots

We keep hearing that the middle class is disappearing but the explainations that the left gives doesn't make any sense.  Nobody is stating the obvious.  The middle class is disappearing because the middle class has stopped doing what previous generations have done to put them in the middle class.  The rich are going to keep on getting richer and the poor will continue being poor.  Why is that you might ask yourself??? You have to look at the habits and lifestyle of each group and the anwers become crystal clear.  Take a look at the “Wealth Inequality In America”. video that describes the way Americans think weath in America should be distributed.  There are a lot of errors in the video but the main one is wealth is not distributed but earned.  The top 10% have more because they have earned more and the bottom 10% have less because they have not worked.  It is sad that in an age of so much technological advancements we still have a population that does not understand basic math.  If I am wrong, please tell me where 2 + 2 does not equal 4.
