Not really. I mean, economics is mostly voodoo science anyway, so it's hard to make a lot of objective statements about any of this, but it's hardly a stretch to suggest that laissez-faire free-market policies are generally better for economic growth.

But, again, none of this is really the point. Every system is flawed in its own ways, and the libertarian approach simply acknowledges that, rather than trying to distort reality and pretend that a "perfect" system is even theoretically possible.
