The govt does play a role: usually a completely after the fact event. Ford was building the Model T when there was a total of 40 miles of paved roads. Govt collected taxes from the successful folks and then later on built some roads to collect even more in taxes. Have we benefitted from research paid for by the govt to build military weapons (nuclear power) or NASA rockets (more tech than we can discuss here). But all that is no reason to trash the hard working and sacrificing family businesses here in America.
