My problem with all this is that the people moving into gentrification zones are the symptom not the cause.
Everyone is trying to get by and everyone aspires to a better life if not for themselves then for their kids. What kind of people begrudge others achieving it? They'd all prefer a race to the bottom is it? They are just as guilty of self interest as the ones they protest despite their violent self righteousness. Meanwhile the true villains sit back and laugh as we jealously fight amongst ourselves and just get richer.
Sorry but this is a crock of crap. The people moving into Shoreditch aren't the working class done good. They're possibly not even middle class either. Perhaps a minority are ones who've landed city jobs. But families? It's where single people move to to have fun. Or couples with a decent income.
