Does industry likewise have a right to create and have enforced by the state contracts which restrict supply and raise prices. May the Airlines, invoking their right to associate, form an organization and contract to hike fairs? May the automakers enter into an agreement to sell their cars at higher prices?
In a perhaps more parallel example, may the pharmaceutical companies enter into a collective bargaining agreement with the health insurers that the health insurers will cover only non-generics or they will not be sold any patented drugs at all?
What justification can there be for permitting labor to enter into such contracts but not business? I cant help but suspect that it is a sympathy for economic populism and the notion that what is bad for the business must be good for the worker.
We must not forget that these restrictions work by driving up the cost of hiring the least advantaged members of our society. A man who could be profitably employed before a collective bargaining agreement may be forced into a lower paying occupation or even out of the labor force entirely after collective bargaining.
