Hey ripper... I might just be being "smarmy" here, but that link you posted clearly says,
"Comparing the economic performance of the European Union and the USA does not lead one to conclude that America has the more dynamic economy, or that it has performed better in the past or will do so in future."
So i think that whole 200 years of free market thing you said was disproven by your own attempt at finding support. A piece of crap like me could be wrong though... As I often tend to read things before jumping to conclusions about them. If only my 19 year old eyes weren't so young! Maybe then I could better understand how you got what you did out of that site! Curses...
Also, I've paid taxes. So I guess that means that I am allowed to have an opinion.
