Erm, no I think you misunderstand... The prices of eggs, beef, electricity, coffee etc etc, both historical and current, all come from the BLS, i.e. the US government.
At any rate, I've had this discussion a number of times already. Based on the data produced by the US government (some of which you believe, while some you don't), nominal median household income in the US has risen 2.05x between 1987 and 2012. During the same period the
AIER Everyday Price Index (EPI), which heavily weighs the everyday consumption items in its basket, rose roughly 2.35x times. So a reasonably conservative estimate is that household incomes have lagged arnd 15% during a 25 year period which included GFC.
Now all of the above comes with the usual caveat, i.e. all of this data (including the EPI) comes from the US govt and therefore is manipulated whichever way your political affiliations imply. FWIW...
