"If I would be a young man again and had to decide how to make my living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber or a peddler in the hope to find that modest degree of independence still available under present circumstances." -- Albert Einstein, The Reporter, 18 November, 1954 Shortly after making this remark, the Plumbers and Steamfitters Union, A.F.L in Washington, D.C voted to grant Einstein an honorary membership.
