The modern international free market economy is a marvelous, interconnected system. Yet if you remove only the electrial switches, the system will collapse. Or if you remove only the rubber products. Or if you remove all the receptionists. Or if you remove all the capacitors.
Or if you remove just one industry among the hundreds that make up the economy: Remove just the stockbrokers. Collapse. Remove just the package delivery services. Collapse. Remove just the gas stations. Collapse. Remove just the farms. Collapse.
The modern free-market economy is irreducibly complex. And yet, despite our great intelligence, no one person - indeed no one committee or soviet or economic design bureau - was ever responsible for designing the modern economy as it exists today. This in spite of the fact that several Communist countries destroyed themselves by trying to do just that. The modern free market economy evolved into its present IC state.
