The problem I see is that although the trend may have started before, Brexit caused the local financial services sector to effectively collapse and move to the Netherlands and Germany. London will never be able to recover that loss in ten generations. Had brexiters not ejected your finance industry, there was probably an opportunity to recover.
As far as I am aware, this is just straight up is not true. Do you have a source for this? Because if the financial sector in the UK halved and moved into the Netherlands and Germany the UK would be doing much, much worse, and Germany much better economically.
