If the non-productive parasites get too demanding and/or threatening, the rest of the country will rise up. And they are getting more demanding and threatening every day. Americans will take a certain amount of cr@p up to a point, and then they react strongly. Just ask the Amerinds, the Germans, and the Japanese.
the Tea Party movement is an example of this to certain degree but I dont think it will go much further than this.
The middle class has become the recipient class as well. The dont realize that these little treats that government gives them cost them much more that they are worth. These treats like Pell Grants are slave chains and the middle class does not see them for what they are.
The politicians wrap our chains in silk and call them pillows and we believe them.
