Aye, the self-congratulatory “Protestant Work Ethic” is not Protestant at all. It was simply the culture of certain places and times which got mixed up with some theology some of the time. Handy, perhaps, but not limited to Protestants and not present in all, or perhaps even most Protestant-majority societies.
However, for the larger view:
Honestly, I think almost all rpevious posters are a little too certain about things. The basic fact is that we don’t have any clue. It might be a one-in-a-million chance. Or it might be just what happens as a matter of course. Or it could be that the steam engine with an adequate power supply was exactly what the doctor ordered, and could have appeared in most places had it worked out like that.
What we can probably say:
Northern Europe had a strong property-rights system in place, which surely helped.
It had a strong industrial focus. This may or may not be important, because the financial systems of Southern Europe were better developed and perhaps would have supported things equally or better if it had gotten started in Italy or something.
Britain in particular had a social system which produced excess and mobile free labor, unlike China.
England was relatively war-free, and when it did make war it was abroad, not at home.
There were useful and useable compact energy supplies waiting to be tapped.
The transportation system was pretty well-developed. Note that just before the Industrial Revolution a very different Transportation Revolution was very much present in America, and to a slightly lesser extent in Britain and France and the germanic lands. Transportation costs even before the invention of railroads were falling by orders of magnitude. As improved shipbuilding, macademized roads, and canals may have made the Ind. Rev. possible and profitable.
