That's my point. Earning a wage 5 or 6 times higher than average is still considered by the OP to be middle class. Something is wrong when the "middle" also includes professionals who earn far higher than average. Western society, particularly London, is too focused on the elites. Everyone who isn't a banker is balled up in the "middle class" catch-all.
For instance, a tax break by government to help "the middle class" shouldn't be helping lawyers and doctors. They aren't middle class. Progressive taxation or benefits should not aid those earning 200k/year.
