Its never one or two things( you can usually tell someones agenda by what they believe the cause was).

I was in Detroit 25 years ago and I remember how destroyed it was. I had never seen anything like it on that scale. I grew up in a "urban community" on the south-side of Chicago, so I had a point of reference. I remember telling my friends to get the f out of here but that was their home and they wanted to do what they could.

Eventually, they moved on. Urban pioneering is a young person game.

PS. in before the move
