I see. If that was your point, what was your strategy in refusing to disclose you point (even when I explicitly asked for it) until now?
Also note that I linked to sources indicating the actual per-capita GDP and GVA of London: under both measures London is far more productive than other regions in the UK. Further note that the reason many wealthy foreigners live in London is because of the UK’s non-taxation of foreign income, so they are unlikely to be a major direct source of tax revenue. Note that even if high London tax revenues are not drawn from UK-sourced income, these taxes are still being collected in London and are still being used to subsidize the rest of the UK. The only difference would be that the subsidizing would be done more by wealthy foreigners and less by UK workers.
