Even celebrities in the UK and particularly the world of media networking are dominated by those who had privileged upbringings with expensive private education followed by Oxbridge.
Yes and if anything it's getting worse. There used to be a lot of 'working class' actors and other celebrities, but now it's rare to find one who isn't among the 7% of the population who are privately educated.
The royal family are a shiny bauble which looks like it’s the lynchpin for the class system but it’s much more entrenched in UK society - you could get rid of the monarch tomorrow and the rich controlling influences of the old money families wouldn’t change one bit.
That's also very true.
Some of the most egalitarian countries in the world, such as the Scandavian nations, are monarchies. While many very unequal societies are republics. Even in countries like France or Italy which abolished their monarchies and peerages, the former aristocrats still retain a lot of power, wealth and influence.
