I suspect most of you aren't old enough to have been driving cars in the 1970's. The 55 mph national speed limit. The general consensus that it was just wrong. And the civil disobedience that sprang from that. It was the nearly complete disregard for that limit that led to it being changed. Once a law or regulation becomes so extreme that it leaves rationality behind, people start to ignore it or find ways to avoid it. I would argue that 9.5% sales tax is having that same effect. Especially when you consider it is on top of Federal income tax. And state. And local. And Social Security. And Medicare. And health care.
"Those who profess to favor freedom, and yet depreciate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle! Power concedes nothing without a demand. It never did, and it never will.
Find out just what people will submit to, and you have found out the exact amount of injustice and wrong which will be imposed upon them; and these will continue until they are resisted with either words or blows, or with both. The limits of tyrants are prescribed by the endurance of those whom they oppress." - Frederick Douglass
