It would of course have to be low enough to not cause significant numbers to leave Baltimore. But there are exceedingly high salaried professionals tied to Baltimore - in the courts, government jobs, hospitals and other institutions. I would also end tax breaks to corporate electoral campaign bribers. Finally, we should replace the residential property tax with a progressive income tax tied to the federal income tax. Baltimore has over the past few years provided very generous tax breaks to corporations embarking on large-scale capital projects locally.
Corporate welfare is humongous and dwarfs legitimate welfare for the poor.
Baltimore should form alliances with the counties and Maryland and with the other states to form a united front against corporate blackmail. We will attract proper businesses to Baltimore when we end the phony war on drug addicts. Crime will then fall dramatically. Democratizing the school board will result in a better educated work force. Baltimore's location and infrastructure, low rents and skilled work force would then be enough to attract and sustain businesses large and small.
