And your dollar bills, under the current system, are taxed both when earned and spent. No difference to you. You are not harmed in any way by the transition.
But to be against such fundamental reform that doesn't hurt you because someone else might do better off than you is a lousy attitude.
And your hypothetical is a bad example, no matter how much you're trying to simplify. It points out the worst possible case. And even in those conditions, the NRST still works out OK for you -- just because it works out better for others doesn't make it less fair or right. You have the same opportunity as anyone else under the new system -- take that lump of cash and invest it to see tax-free growth. Then you too will have new dollar bills that are untaxed when earned.
