I have been in manufacturing for many years, starting with an internship in Ford’s Dearborn plant in the 70’s. I would never work in a unionized shop because of all of the inefficiencies that were ‘won’ by the unions in negotiation with management.
At the same time, I share your dismay at the wealth concentration that occurs when labor is exploited.
The best that I can come up with is legally mandated minimum compensation, but that is open to corruption as well.
The question is: how do you get the capital voice and the labor voice working together for both short and long term success for the enterprise, employees, and investors?
You’ve stated a convincing case for labor’s need to have power. How does that power not be abused, just as capital’s power is now being abused?
