Quote from piezoe:
Right on Zebra. The government has its own method of computing the inflation rate which takes into account the nebulous fudge factor of "quality". The change in the method used to compute inflation was, i think, introduced during the Reagan administration, and had the effect of reducing the official figure. This, naturally, is highly beneficial from a political standpoint during times of heavy deficit spending, such as then and now. As entitlements and TIPS are indexed using the official figure it is easy to understand how reducing that figure can save the Treasury billions, to say nothing of the beneficial effect on servicing the debt. That is to say, it is helpful when one wants to use stealth inflation to inflate their way out of debt, as is the situation at present. Just as a long call and short put is a synthetic for long stock, inflation is a synthetic for taxation.
