Once government has succeeded in getting your money, you can bet they will not give it back, even if the original "need" for the tax has gone away.
I've always thought that any "tax cut", which is always highly publicized, is secretly compensated back to the government by raising a thousand other current taxes by miniscule amounts in a way that no one will notice. Call me cynical.
We see it happening here ,, it's called a parcel tax, a library tax, a supplemental district fee, a toll fee, you name it, it comes in many forms.. all accomplish much the same and all of course are temporary. ;-).
