anything based on a global commodity like lead is going to go up - since the value of the dollar is down.
It simply takes more of the cheaper dollars to buy a given quantity of lead.
Unforunately we have to keep our dollars cheap so we can afford to pay off our debt!
Doesn't matter if we owe trillions if we can make a trillion dollars only be "worth" a billion.
Of course, the way it's supposed to work is we all should be earning more dollars to offset the difference. But that requires a real economy - not a government driven one.
