I agree that the most important and realistic thing to focus on would be to clean up the neighborhood. It needs it.
I have no illusions about this neighborhood, it is an affordable and safe lower middle class family neighborhood, good public transit, with a strong immigrant community. Other than some of the gorgeous architecture, the only outstanding feature I believe is the incredible/authentic ethnic food. To partake in anything very interesting, or entertainment related I always need to leave the neighborhood, it's a fact.
Let us not forget the H- word.
The people responsible for changing certain neighborhoods in Brooklyn you have been discussing, are Hipsters.
The truth is, young, single, artistic types do not flock and or strive to live in Jackson Heights.
Hipsters transformed Williamsburg, I believe, because they were incredibly passsionate about the neighborhood, and only with great passion, can residents transform a neighborhood.
Just look at how Bushwick has started to evolve, do you know why? The middle class Hipsters who could no longer afford Williamsburg moved there, again , there's something about Brooklyn that drives young people to transform it, make it their own.
Take Care.
