Disproportionality is certainly okay here when it is blacks that benefit, yet when it comes to things like convictions and incarcerations, it is racism.
I would suggest that if the cutback impact is particularly damaging to 'blacks' as a race rather than one would think of public functionary as a servant - of no particular race or creed, there is an easy remedy to this complaint.
Reduce the disproportionality of their representation in public sector jobs. There, job done, no disproportionality, no disproportionate affects due to cuts. It is simple.
An anecdote:
After Hurricane Ike devastated Galveston, TX in 2008 (among other cities), there was a big push to NOT REBUILD the projects - the Federal government eventually became involved and came down hard against it and block this good idea to have displaced families live all around the city, closer to transportation and jobs and not all bunched together in a project. Democrats must keep as many dependent people and isolated.
