It's cheaper now in the USA than it's ever been, BUT we don't know if we're really paying the full long-term price for it, or if someone else will have to pay it later.
Like buying "Made in China" stuff manufactured with communist slave labor. Sure, it's cheap to buy, but look what the REAL price is ... loss of American jobs, dependence for necessities like machines and medicine on a country whose long-term plans are NOT in our best interests.
Or, like I've mentioned, the price of cotton and tobacco 160 years ago. Dirt cheap, because it was made with slave labor. But we're paying the REAL price today, as a glance at the news will indicate.
So who knows what the REAL price of gasoline is? All I can do right now is what I AM doing - burn as little of it as possible, with a home "fleet average MPG" of over 40 MPG (little gallons, 50 MPG in your money), pay the pump price, and get ready when the real bill comes due, if I'm even still here. Might be my great-grandchildren.
