My hero, who answered the question 'what is the best government for commerce?' is the late Mancur Olson.
He argued, persuasively to me, that government was like a saucer with a deep cup holding spot in the middle and a gentle upward flange on the outside. The deep spot represented governments that are too strong and will seize successful businesses to give to friends, family and members of the ruling class. The outer upper-ward flange is anarchy where the rule of law is too weak and property rights are not protected.
The
United States has a government, more accurately a melange of
governments, that are on the flat part of the saucer, not too strong and
not too weak. Remember, the Jim Crow state governments in the South
kept commerce stifled for nearly 100 years after the Civil War.
There can be many other forms of government that are good for commerce. Our government was pretty much an accident of Holland creating Manhattan, The Dutch invading England, the religious wars driving a dissident commercial class out of England and letting the whole new American colonies stew in relative isolation for 300 years.
There can be other forms of government that would be good for commerce, not too weak, not too strong....they just haven't arrived yet.
