The big chains won't run risky or unprofitable stores. It's the communities that will be hurt by this. Despite interest-free loans and over $100 million in federal funding, Baltimore still hasn't recovered from the 2015 Freddie Gray riots.[1] Moreover: government funding is a rather blunt tool, and directing it at a city tends to cause most of the money to flow to the nicer parts of town. That's what happened in Ferguson.[2]
Riots tend to widen the disparities, not reduce them.
