The MID barely cancels out my property taxes. Imagine if your investment accounts had to pay 1% tax every year based on its current worth even if you didn't realize any profits.
Imagine the fact that property taxes pay for a lot of that. Now imagine house values plummeting because you removed the deduction and you've put the funding for all of that in peril.
That seems like the wrong way to think about things. That funding, then, is predicated on inflated, consequently inaccurate, housing/property values. When the bubble bursts for any reason the funding source will be reduced.
Critical services banking on a bubble to sustain themselves is just a terrible (though often done) idea. Eliminating the bubble earlier and getting accurate valuations before becoming dependent on the inflated amount (and suffering from austerity efforts later) would be a much better (and rarely done) plan.
