Where we are againt at the point that these changes dont happen over night, as there is oportunity costs associated with moving.

until 1940 London was a the centre of a global empire, albeit a dying one. Then when the last remains of the empire died off, the EU predeccessory came and Thatchers violent neoliberalization to safe London as a finance hub.

But unless we see another push like Thatchers, that this time would basically need to enslave the average Britain to the markets, i don't see how London will keep itself afloat in the long run.
