There is less of the population working now than at point in history of this country, people have just given up looking for work. Or they just don't want to work, when uncle sugar can give out handouts and Obama phones...
Socialism is an disease that eats countries from the inside out, a deterioration of society...
I blame a lot of that on Nixon, Reagan, George hw Bush trade policies and policies of transferring the wealth from the small business creating middle class to the most wealthy...
I'd go back to 40's, 50's and 60's policies in which Bernie sanders kind of wants to do. Sorry, but a corporation capable of buying out the rest of the field and closing the door on a new companies ability to compete is bad for our economy...I'll admit that a lot of the better jobs just aint here but you're not clean.
Also, socialism through the unions and regulations built the middle class to begin with. Look at Norway, Britain, Germany, etc to see that it isn't what you say it is.
Here is a little test for you...When did America have the bigger by percentage middle class with higher per capita?
1890 or 1950.
