Are taxes ever fair? Alot of the buildings in my town had thier windows removed and filled in with stone because a few hundred years ago there was a window tax. No really. That's not far off taxing fresh air for breathing.
I think Fry's Rebellion here was over a similar tax plan.
In Greece they never finish building their houses to avoid paying property taxes. That and other ways of avoiding taxes there screwed over their economy.
