Kelja on Thu has it right.
"Core Inflation" a gambit.

As a retired citizen, who stands to gain or lose in Social Security Payments based on the CPI, I'd like to quote just a few increases in my own budget, that are excluded from the current 2.3% core increase that will represent inflation adjustment..

healthcare - 8.4%
healthcare supplement 9.6%
medicare part D - 12.5%
electric bill 16.7 increase
gas bill 9.4% increase
nursing home insurance 12.7%
water/sewer 40% increase
food (from budget actuals) 19%
Gas... same- but from 10,000 mi. to 7,500
house insurance (inland Florida no Hurricanes) 137.5%
fire insurance 13.9% increase
house taxes 7.1% increase

now... as to the "core". That $700 laptop from last year is now only $549, but I can't afford it anyway... and the intrinsic increased value of my new shoes that should last longer, won't do me that much good, because I won't live that long.
