Earlier quoted context omitted.
One thing I never see mentioned in this debate is the fact that America was a British colony as well, and colonial status definitely drained American wealth for centuries (though obviously, the occupation of India was far more brutal). But I think it's highly unlikely that America ever would've become a superpower without the benefit of British culture, institutions, and law.
The wealth stayed in America. Also don't forget the prior free labour.
Not true. The British did the same thing here that they did in India--prevent the development of local industry so that raw materials from the colonies would be shipped back to England for manufacturing and sold back to the Americas.
