...but I have to agree more vociferousely w/ kerwynk. The example of the dancers who stayed but did not want to have sex, so they either left or felt pressured to stay because of economic need, is a perfect example of the "free market" theory falling apart in reality. This is an argument I've had many times with self-identified free market Libertarians, who argue that a truly free market will solve everything. Unfortunately it doesn't work that way... instead we see scenarious like this one. Or, to use an example I'm sure we're all familiar with, we see locally-owned small businesses having to close their doors because they can't compete with large national Big Box stores.
Keep in mind I say this as someone who is not anti-capitalism! But I do think the free market might be a ncie theory, but as we know, reality is usually a different and much more complex matter entirely. (Besides, the notion of a free market is based on a fallacy anyway... who establishes this "free" market? But that's another rant for another time!)
