An Extension of Unions
So, Nathan was nice enough to point out that all the great economists say that unions are OK. That's fine, I don't care. In my current area of study, unions depress pay and fundamentally stifle the quality of the supply of labor. (Don't be verbose...)
For instance, in education, unions serve to create across-the-board equally scheduled pay based on tenure. Simultaneously, they advocate iron-clad job security, and even in states that do not have unions, the State does a good job of securing even pay and iron-clad security. This prevents us from paying people for their merit and firing the ones not worth paying.
The abolition of unions would increase wages for those better-suited for teaching and put some not-as-well-suited out of a job (but they don't need to be teaching our kids anyway). In other words (and this is important):
It would more-efficiently allocate wages.
As the science of economics seeks study the maximization of wealth through the efficient allocation of resources, this seems like a good step for policy-makers to take.
The extension of the argument, as suggested by Nathan: "The existence of unions, though beneficial in the short run, is ultimately detrimental to the individual." Brilliant! And almost Keynsian. But I won't tell any of your libby friends. Hush, hush.
My extension to his: "Yes, and unions are ultimately detrimental to society. As it is unfair to the individual, it is unfair to all collectively: the ones working for a depressed wage may be better suited for and earn more in another position, or at the very least will consume less of our resources; the ones not working in whatever position (teacher in my above example) may now have another option that replaces their first or even second choice of a career, changing the whole set of opportunity costs the individual weighs in the efficient allocation of his own fiscal or human capital."
