I don't get why people throw around the word "capitalism" like that. The U.S. legal system isn't organized around "capitalism" in any real way.

The U.S. historically was a liberal republic, though lately the republicanism had given way to a stronger administrative state on all levels.

And it's that that really influences how things are influenced with respect to urban development: regulators, HUD, local zoning boards, transportation planning, transportation energy regulations, etc. Not much of that screams "private control of the means of production" or even "free market".
