Why Did the Industrial Revolution Come to England?

Tyler Cowen quoting Michael Hart:

1. England had a high average IQ
2. England had a relatively high population (compared say to the Nordic countries)
3. England did not have slavery
4. England had intellectual ferment
5. Colonies added to the intellectual ferment of England
6. Unlike Germany or Italy, England was not politically fragmented
7. England had abundant iron ore and coal
8. England had relatively secure property rights

Hart stresses that in Europe only England had all these factors operating in its favor.
