Which taxes hit the poor hardest-those of local, state, or federal governments?

The taxes which hit the poor hardest are those of local and state governments.

Federal government taxes are progressive, which means that people are taxed based on their income - this means that rich people have to pay higher taxes than poor people. On the other hand, local and state taxes are regressive, meaning the taxes are based according to the service bought - it's the same for the rich and the poor, but given that poor people earn much less money than the rich, they will be affected more direly.
