They are hindered by their idiotic monarchy and arrogant class system.
The monarchy is not idiotic. For Americans maybe, but not for the Brits.
And their "arrogant class system"? The old system is long gone - what's left of the aristocracy is made up of inheritors who are forced to exhibit the stately family home to the tourists.
The one you refer to is made up of entertainment types, media elites and "intellectuals" with a political bent. Sound familiar? It should.
