The main issue in London is migration, and fundamentally that is made up of economic refugees. People fleeing from the economic messes of their own countries. I think you can split this group down into two.
First, the people fleeing for work. Primarily from the Eurozone. They tend to be the productive, and the effect on the counties they are leaving isn’t good either. They lose the tax payers that pay in more than they take out because they are young. That causes more instability and economic woes.
Second are the rich looking for a safe haven. From Greece to Russia, people know what states do when desperate. They just take people’s money. See Cyprus for the taking from bank accounts without permission. See the IMF plans for a 15% raid on bank accounts, just to stop the Eurozone from getting worse. [In the UK there are plans for the tax man to do the same, heck they even take your organs now without permission]. So the rich buy an expensive property in the UK. If it all goes Pete Tong (wrong), then they can get on a plane or boat, arrive in London, and have a good life. It is insurance against the inevitable.
