You missed the US military and how US economy is built upon the strong arming of almost all other nations on earth over access to resources, commodities and markets.

The idea that free markets are the ideal is fine in theory until you acknowledge that humans for groups called nation states and these nation states are the mechanisms by which territory and resources are competed for.

The US is at best a crony capitalist empire maintaining its wealth via military power and domination of global institutions and protocols. Without that centralised power domination the US would be very swiftly insolvent.
