"History" refers to not private vs public property but to the unfortunate propensity humans have to do unpleasant things to one another. People aren't all bad. But they are occasionally, and those occasions are significant. People might be nice to you your entire life, but you only need to get killed once to really bring your averages down.
Dunno about enclosure of common land leading to reduction in productivity. Do you have data? Seems pretty positively correlated, though obviously that doesn't prove causation. I'll try to dig up some data as well.
Also not sure as to whether theoretically it makes more sense that social and environmental costs are higher under private property systems. Certainly non-democratic regimes have been large polluters. Ostensibly collectivist ones too. And what about the tragedy of the commons type problems?
Think I've already conceded that collectivist entities exist successfully within capitalist systems. Hell, we've just witnessed the largest nationalisation in history right in what many consider to be the heart of global capitalism.
The market is also a collectivist entity, in the sense that it is just another institution or set of institutions supported by society. And of course culture matters. Norms matter. Institutions matter. It's all one and the same thing.
I only wanted to say that Hernando de Soto is a very talented economist with a very important idea. Read his book. It's good. Furthermore, it's short and plainly written. If you are a liberal who believes in that the government can and should intervene to positively affect the lives of the poor/marginalised or even the whole of society, then... Well, I think you'll largely approve. As de Soto says, it's not about whether capitalism is God's vehicle on earth, it's just about what works. Maybe it's a sweeping statement, but keeping the poor outside the legal system seems unlikely to bring them many advantages any time soon.
