We can be certain the CPI has been corrupted since at least the Boskin commission in 1996. Taxes and entitlements are tied to inflation. The Boskin commission determined if they could find the CPI was over-stated by 1.1% they could save $1 Trillion over 10 years. Magically, with no new research, they came up with a justification to lower the CPI estimate by 1.1%. Raising taxes and cutting Social Security without getting caught is the third rail of politics. The amount of pressure to find ways to do this is immense. This is the level of corruption you are dealing with. We are not even on a path from "here" to a place where the CPI is an actual fair estimation of inflation. Most people don't even know this is a problem. It's too complicated for regular folks to even deal with and all the establishment political figures are in on it, so they obviously won't draw attention to it.
