Actually it does. Savings are not treated any differently under the nrst with respect to purchasing power. The only difference is that investment income is no longer taxed... your savings will grow faster. There is no reduction in purchasing power because prices will remain stable.
Forget how they "treat" my savings. How I SPEND my savings is the issue. The price of my new car, golf clubs and other things. Let me guess,,,they will cost less,,,right? And you personally will establish a fund to reimburse me for the difference in the most unlikely scenerio that you are wrong?
