I'm not convinced by your second one. Why didn't states like Portugal industrialise equally quickly? Or within America, why didn't states with more slaves grow faster? Germany has no history of slavery, and the same is true for modern industrialisation transitions like South Korea and China.
The topic has been studied in great detail in economic history. The consensus seems to be that however horrible slavery was, it wasn't fundamental to industrialisation.
If you are making profit to support a lavish lifestyle relative to your local peers and (crucially) there is no free market value of your laborers' labor, then what incentive do you have to apply innovation?
Some (cotton gin), but certainly less than a free (in all senses of the word) labor market where a shortage of workers leads to increased wages and a push towards mechanization.
I agree. It is my understanding that the Romans were in a good position to develop a usable steam engine, but never had enough motivation to do so, because slave labor was cheaper.
Germany has no history of slavery
We'll just conveniently ignore the war years, gotcha.Also take a look at what happened in the Sud west if you think Colonial Germany didn't have slaves
A very interesting related book that I've read about that period and which I'd recommend to everyone generally interested in economic and social history is E. P. Thompson's "The Making of the English Working Class" (https://en.wikipedia.org/wiki/The_Making_of_the_English_Work...). I'm generally leaning on the right side of politics and economics (I'm a sympathizer of both Bentham and Benjamin Constant, who are not receiving very kind words in this book), but I found it super interesting and I find it intellectual honest to try and and understand opinions (and related facts) coming from multiple sides of the story.
It's always been my understanding that _wool_ had been the early carrier of the industrial revolution? That by the time cotton entered that picture, the revolution was well underway?
Exactly. Now, lets look at some of the causes of the first Industrial Revolution
First, large tracts of lands in Britain, largely held in the commons, were stolen from the peasantry and given to private individuals and landlords, as part of the Enclosure movement. This forced the peasants to look for work in cities en masse, providing cheap labor for the capitalists.
Second, Britain's African Slave trade constituted a big part of the early accumulation of capital that made the revolution possible.
Cheap cotton from the colonization of India as well that produced by the slave labor in North America fueled the textile industry, which was at the heart of the industrial revolution. India's share of the world economy fell from 20% to less than 5%, chiefly because the capital required for industrialization was siphoned off to England
