Why the huge crusade on inflation? It is supposed to exist, and it does in all healthy economies. Certainly, very high or uncontrolled inflation is bad, but inflation is, by definition, only a nominal value. All real values increase to compensate. It does not eat away retirement savings, because the interest you are receiving on that retirement account is only as high as it is because of inflation. If the real interest rate is 6%, and inflation is 2%, your return will definitely be 8%. If you get rid of inflation, you just slow the rate of income growth and the interest rate as well. It does, literally, nothing except remove some of the options of the federal government.
For example, since there is inflation, the government can lower interest rates to near 0% to achieve a similar effect to negative interest rates (which would probably not go over too well). Inflation provides a buffer and a tool to keep the economy running smoothly.
Also, devaluing a currency is the most reliable, painless way to stimulate a global economy. It doesn't change your purchasing power, because you are supposed to get paid more to compensate (or now, simply not paid less). The idea that inflation eats away savings is a complete myth, unless you hide cash under a mattress, in which case you have bigger problems.
