I think a possible risk when more federal aid is given to cities is C. HIGHER TAXES IN THE STATES.
When federal aid is given, there will be more money for public services. Money that will still be under local control but overseen by the federal government.
I don't think that higher taxes in the cities will be imposed. The reason why federal aid is needed is because the city has less money for their public services. This means that their tax collection may be insufficient or there are lesser number of employed individuals and businesses who pays taxes.
The states will shoulder the additional federal aid given to cities and they compensate it by giving higher taxes in the states.
