I just know that people in other countries manage to come together around issues by the tens of thousands and one of the most populous nations on the planet has trouble coming together by the tens.
I believe that is another value to the PTB of union busting. Congress passed the Wagner Act, creating the National Labor Relations Board, among other things, on 1935 to help address unequal bargaining power between people desperate for jobs and employers. Twelve years later, in 1947, Congress passed the Taft Hartley Act, making the Wagner Act "fair and balanced" for employers.
http://en.wikipedia.org/wiki/Labor_Management_Relations_Act_of_1947Truman vetoed Taft Hartley, but Congress overrode his veto, which means many Democrats had to have sided with Republicans on Taft Hartley. And, while Truman vetoed Taft Hartley, after his veto was overridden, he used it again and again. Given my relatively new found cynicism, that leads me to wonder if the veto wasn't kabuki.
