Where have pure free markets ever resulted in anything other than failure?

All wealthy and successful empire have been a combination of free enterprise and judicious government.

The British Empire combined a strong military, mostly Navy, with strong legal and monetary systems and well regulated financial markets.

The US has succeeded the British Empire and is equally reliant upon military dominance and control of international institutions and protocols to maintain its hegemony and wealth. Most of the US GDP is derived from 'financial services and manufacture of military equipment- debt and death.

The control of trade routes, access to commodities and markets and protection of territory are all significant factors where free markets alone will always fail without strong partnership with government.
