England was the top imperialist power until the united $tates displaced it definitively after World War II. England is a place where a majority of the population is bourgeois, mostly from the traditional petty-bourgeoisie and the labor aristocracy.
In many ways the decadence of imperialism is more advanced in England than the united $tates, because of England's decline from top dog status. Before we speculate on the nature of imperialist decline, we should always check by looking at the facts of England first.
