I don’t understand why workers aren’t pre-organized. My concept of a union is a wage-setter, but this wage-setting should occur prior to employment. Prior to employment a worker should join a union. The union analyzes the profitability of corporations and sets the wages of employees based on that profitability.
The way this system would work is that corporations wouldn’t deal with individuals. If there are multiple collectives the corporations could wage-compete for the “best deal” among the unions, and the union furnishes the worker.
