They won't let you in. You need to be a multi-Billionaire. IQ doesn't matter. You need to have the correct surname and lineage.
If we were to have a revolution, which I think I posted on here a long time ago about, you stand a chance of getting in at the beginning and creating a dynasty. But... I'd prefer to have a utopian society based on socialism. If I earned 1 Million pounds a year. I would happily pay 75 percent tax on anything over. The 1% pay no tax.
Too deep?
