the cpi does include gasoline, but they have factored it out because of the high run up... that's why it is worthless now, i'll tell you why....
it's composed of all the basic nessessities to live.... groceries, gas, car, rent, etc... then they decide "oh, gas is too volatile now, let's calculate cpi without gas" ... then they're like, "oh, groceries are going up because of gas, so lets get rid of that" ... what's next? home prices are plummetting making rent increase nationwide, so lets get rid of that too?? ( rent is the largest contributor of the cpi) ... basically the whole thing is worthless.
the fed stopped publishing the money index numbers (so we wouldn't know how much money they are printing), they're basically bullshitting everything now in hopes they can keep inflation low and also prevent the economy from falling into recession. they can't have both. i think we'll either see a huge surge in commodities prices, or a mild recession overall with an ugly downturn in real estate, one or the other.
btw if you didn't know, venezuala stopped selling oil in USD$ and is now only selling oil in euros, russia will stop selling in dollars by about the middle of next year and sell in their new rubles now that they restructured their currency, and by 2010 all the middle eastern nations will only trade oil in a unified middle eastern currency they're developing. no one will want to trade oil for USD$ anymore which means the US won't be able to manipulate their currency and commodities anymore. what will that mean? just wait and see, we'll have $200/barrel oil, $1500/oz gold and $3000/oz platinum by 2012 or so.
