Disparate impact... it's going to be with us for a while. Might as well get used to it. Black people are generally less intelligent than others and it's our fault.
While you state that black people are generally less intelligent then others, I think these politicians thoughts are a big drive towards that... they are in effect stating that poor neighborhoods are incapable of reporting their own pothole problems. In the end, the "Street Bump" app is another avenue of personal responsibility - people took the initiative to improve their driving route, installed an app to report problems, and ran that app to ensure the problems were reported. In poorer neighborhoods, people are not taking the personal responsibility to report the problems. They can call in to report problems, and by reporting those in sufficient numbers (similar to the app) Boston's street maintenance crews could be alerted. They don't, though, because they have been conditioned over generations to believe they don't matter and it requires someone else to fix their "problems".
In the end, the politicians are stating the poor people / black people / whatever group of people are incapable of taking responsibility (unlike those wealthy people), so the Government must hold their hand and make things easier for them. Yes, it will be with us for a while, and short of a major event nothing will change it.
