Labor unions brought many positive changes to America, but at a very high cost. Violence and corruption have permeated unions and, in many cases, hampered the incentive to excel. Virtually nothing can remove a paying union member from a job, regardless of performance or behavior. Additionally, Americans are denied the right to work without paying union dues.
Socialist, Marxist, communist and progressive infiltration and ideology spilled into the government due to massive and unprecedented political contributions from unions. Rampant racism kept blacks from joining and laws like the Davis-Bacon Act in 1931, further prevented non-unionized blacks and immigrant laborers from competing with unionized white workers for scarce jobs during the Depression.
Has it all been worth it? Do the victories of unions in the workplace outweigh the heavy cost? Unions had their place and time in American history, but that time may well have passed.
