It's interesting but sad watching that creativity vanish as the rents rise. There's more money here now, but less creativity.
I think this apparent contradiction is resolved by asking "who had the time to be creative?". When rents were low, artists could make ends meet and still have time to create. As rents are rising, the artists are pushed out, or forced to spend more time making money. The new tenants are people earning decent money, who again are either working too hard to create, or are not "artistic" in that sense (me included).
The old squats and communal housing are being redeveloped, the graffiti-covered walls are being repainted so the houses they cover keep their value. The focus moves from "poor but sexy" to "let's make lots of money". Everyone is richer, except the culture.
