The village I grew up in during the 70s looked quite nice back then, but is probably falling apart today.
That's the way cities usually work... in cycles.
There's gentrification, then a more hip place is built elsewhere, people start moving out, property gets damaged, rents fall, and when the place is crumbling, poor people move in, then artist and gays (simply because they are usually not concerned by risk... there's nothing sex related in the process, it just happens to be that way) find that there's something to do with the place and start fixing it up, once it gets nice and there are cool small cafés and boutiques, the rich start taking notice and begin to move in, demand grows, rents go up, the poor can't afford to stay there anymore and are forced out, and the cycle keeps on going.
And then, the artist get tired of it all and move to Portland
