> Flight from London is happening. It's already happened in a large way as well
None of the people I've known who moved out of London did so because of crime or safety. They almost invariably moved because they could pay for a tiny place in the city and commute for over an hour each way or they could pay the same for a larger place outside the city and commute the same length of time on the train.
But you've not cited any sources either, so don't pretend that you're some paragon of statistical analysis. You've just said things like "I wish I didn't grow up in an area where I know that to be true," which is pure anecdote. Others in this comments thread have provided sources. Why haven't you?
This opinion is coming to you directly from the burned out debris formerly known as Seattle, so I think I’m pretty good at identifying imaginary disaster zones.
