One has to think about what service the city provided in order to receive the income (tax). I don't know of one, but perhaps there is one. Usually, rational people think of taxing for a service (e.g. city builds the roads and taxpayer pays for them).
Interestingly, there is a requirement in Texas that the city not be able to recover more than the cost of the service. In other words, they can't provide a dumpster on your property for $600/month, if they can only rationalize a cost to them of $100/month. That would be a new tax, which can only be voted on.
But this is DUmmie land...Chicago.
They can rationalize any tax number for what the Rats think that they deserve of your money.
