Why do so many self-proclaimed libertarians and leading figures such as Ron Paul support Right to Work laws? It seems to me to be inherently anti-libertarian, and I don't buy the "it results in more individual freedom for workers" argument.
Now, I know you're coming from a more pro-union perspective, and to a point, I agree, unions are important to ensure workers get a fair shake. But just as important, are the strike-breakers and non-union workers. They provide a downward pressure on wages that keeps the union shop from going too far above market value for a particular labor. A closed shop, which is what these laws are intended to prevent, will allow the wage to far exceed market value, causing the company to lose money, either by paying too much on wages, or by having to raise the price of it's product too much and being unable to sell it.
Of course, the laws
are inherently anti-libertarian, in that they prevent businesses and unions from engaging in voluntary behavior (setting up a closed shop), and I would prefer the market be allowed to prevent closed shops by driving those that use them out of business when the union demands wages too high to support.
