Not exactly. I believe I said, why is your labor worth more simply because your employer made a profit. We no longer have child labor, sweat shops and 20-hour workdays of the 1930s. The labor movement of 100 years ago brought about 40-hour workweek, paid time off, OSHA, the NLRB and a fair days pay as determined by the labor market. What the unions were founded for has come to pass. Labor unions have outlived their usefulness. Not only because government standards now protect workers but mostly because, unlike the 1930s, we are now living in a global economy with global competition.
Look at the history. In the 50s and well into the 60s, the only industrial nation on the planet was the United States. World War 2 destroyed the European and Asian economies, and it took decades before those countries were able to export and become world trading partners. The big three built cars with what they openly called planned obsolescence. They were built to last 3-5 years. Not until the early 70s did foreign competition force them to build quality cars at reasonable prices.
