DiBlasio has destroyed the city.
This was totally predictable.
A good mayor can turn it around—but in the meantime it is wise for folks who can to skedaddle.
Yet with the middle class and higher American-born leaving, the city voter base is getting even more leftist and more likely to re-elect s/him. They have the votes now to embrace 100% socialism at the city level, even print their own currency to solve all their problems. While socialism enables the crappiest to rise to the top, there are reasons socialism doesn't last very long at just the city level. But there's still enough time to loot the sinking ship and prepare an overseas escape plan for the soon-to-be rich leaders. Swiss banks love the socialist end state.
