As for London Weighting, that's just part of peoples' wages - it's paid
for by the employers, yet the employers are quite happy to locate
themselves in London, so obviously they think it's worth it.
If London Weighting was stopped, or other places paid the same, I'm sure
the house price differential would fall as less people would be able to
compete for housing stock. Making other cities more attractive.
