Where did you get 6 trillion. At least say something halfway plausible.
Certainly enough blame to go around, Bush brought huge deficits, then Obama came along and one-upped him. As to the science of Ethanol, of course it does not treat your car as well as Gasoline, and that is a concern. Perhaps the automakers can make some adjustment, as they have with E-85, but that does not help the people with older vehicles.
What's "halfway" to you? There are estimates that the debt (municipal bonds + treasuries) equals more than $85 Trillion. And that may or may not include unfunded pensions dumped on the public debt by GM, Chrysler, airlines, etc. and "guaranteed" by "congress." 40-50 years goiing down the wrong road - leading the whole PLANET down the wrong road and every 4 years, a new face, same song and dance, and no retracement. So, my question to you: What do you do if you are "halfway" to the event horizon of an inhospitable black hole? jm
