Since you dispute the validity of Bernie Sanders' assertions, I went to the Bureau Of Labor Statistics and researched the average hourly earnings in the entire private sector from 1964-2005. Here is the data I found:



Since it is more or less an interactive function like Java, I will tell you how I compiled it so you can do the same. First, visit this weblink:

I then checkmarked the box for Constant (1982) Dollars so that the data wouldn't be affected by fluctuations in the Dollar, but would closely represent the buying power that an hour of labor actually has. This is tied to the CPI and I am sure you should be able to understand the relevance of that.

When you hit the "Retrieve Data" button, it will take you to a new servlet page with 1996-2006 data. I then changed the dates to start from 1964 and end at 2005. I also checked the box that says "Include Graphs (new)". Then I hit the GO button and that produced the new table.

As the BLS confirmed, average hourly earnings in the private sector were rising from 1964 to 1973, wherein they then took a turn and started falling.

It's still sad that you have to attack the source. After reading Bernie Sander's biography on that side, it would be no wonder that anyone who defends big business would not like the guy. His constituents, however, do. He was re-elected as an Independent seven times. Of course none of that seems relevant to you as he is just "some socialist".

Here's a tip for you: Next time you want to debunk any data that someone represents to be factual information, provide some counter-evidence instead of attacking your opponent or the sources of the data. Debating sources of data instead of the data itself only serves to reinforce the belief that facts are made true based upon who asserts them.
