Jubak's full of it, IMO. The "real" inflation rate is probably close to 8%. But how can we tell for sure? The Powers lie about it for their own ends.
If you've kept track of the rising cost of energy, insurance, food, housing, college tuition, movie tickets, etc... you'll see the cost of "everything except wages" is going up sharply while all along the Gummint claims "little or no inflation". We're not all stupid enough to buy their bilge.
