Good try again.

Ah so now we’re back to ignoring that changing the character of the CPI (just like changing the character of the unemployment rate) eliminates comparing apples to apples. By replacing set standards with soft morphing standards such as hedonics and the substitution effect, the CPI can not longer be reliably used to evaluate return on investment nor how one’s income stands up to inflation.

(FYI the PE uses an enhanced form of the substitution effect.)

OK, we're talking about the PCE and you're saying you don't like its 'substitution effect'.  

People who say things like this and aren't just making it up have actually checked, and can show a BEA link explaining the actual effect they're objecting to.  It's really easy to believe you haven't a clue here, please clear this up and show us something from the Commerce Dept. showing the effect you you're talking about and explain in your own words what it should be.

If the CPI's really important to you, you can always start some other thread and have a good rant over there.

I didn't realize it was ever used.
