It's the media and common populace that (1) has a lower IQ (democracy more widely accessible) encouraging talking down; and (2) demands that muppets have equal opportunity to enter politics as the well-educated élite.

We could give multiples higher salary to MPs, stack the commons with the best Cambridge, Oxford, Imperial, LSE, etc. have to offer ... but you can't do that, because matey earning a living wage or whatever already thinks they're grossly overpaid and that extra income besides their MP salary should be illegal - when a software engineer could earn more. So woman of the people who left school at sixteen to work retail gets his vote, that's who we need in power, not these educated toffs.
