What an innovative idea! Here in the states, economic indicators are a great proxy for many other aspects. Maybe we could do a trial in Montgomery, Alabama, surely nothing would go wrong.
It would be helpful to us non-US persons if you'd explain what signal you're proxying with "Montgomery, Alabama". As it is this means nothing to a large number of people reading your comment.
I think they are referring to Rosa Parks, where the economic difference would lead to segregation.
