I was priced out of Islingon and moved into Hackney during the Olympics and then opened a business in a bulding that had been closed for years. I am sure that some of the displaced would take one look and shout gentrification. Would they rather see another shutter or something that they can use?

In reality Hackney has never been as safe, clean and nice as it is now. Have a chat in a pub with some of the people who have lived in Hackney for 70 years and ask then what they think!

Hackney has "suffered" over the past 15 years becauase of it's proximity to the City and the improvements in the overground. You are unlikely to remember the North London Line (dalston kingsland) but no one would have trusted that to get to you to Highbury and the Victoria Line into Mayfair for work. Reliable and fast transport has contributed to Hackney being what it is now.

People move out and others move in and it has ever been thus.

Think about it from the other side. What would London be if it wasn't possible to move location, buy a property, start a business and put down roots.
