I’m working my way through the excellent John Ferling book “Jefferson and Hamilton: The Rivalry That Forged a Nation” which devotes tens of pages of ink to Alexander Hamilton and Thomas Jefferson’s differences on the economic relationship between the working man and his government.
Hamilton loved the rise of American cities which could harness efficiency through large markets. Want to become a dentist? Do it in a city with 100,000 rather than 1,000 because there are a million more cavities for you to fill. Want to build up factory resources? Same premise, do it where adding 200 workers only requires you to find .2% rather than 20% of the population. Ease of scalability is the proven formula for improving living standards dramatically within a generation.
