We will probably start seeing some serious changes in attitude pretty soon. All these corporate interests are sleeping together for starters, and the Green lobby has slipped under the sheets with them. Now that they've found a way to engineer a plausible reason to boost the price of diesel far beyond gasoline they'll suddenly become much more 'acceptable', trust me on that one.
I saw diesel for $3.69 gallon yesterday, and no blasted reason it should be above $2.50 including taxes, except for NEW ULSD regs! Boys, we got screwed, and it ain't over yet. What a crock....and as a matter of fact it should still be about $1.99 gallon.
You better start figuring on it hitting $5.00 gallon pretty soon because the people have fully bent over to a phoney environmental lobby led by anti-industrial, anti-American entities. If you live another 10 years you'll see $8.00 gallon, because that's their target long-term price. Write that on the wall somewhere and look at it in a few years. Head shaking optional.
