A level playing field is what we all need.
Understanding that Ethanol is not the only form of motor fuel subsidized is a step in that direction.
I was just pointing out that what some would call an oilpatch subsidy is actually a roundabout State subsidy. More or less: “What the Depletion Allowance giveth, Oklahoma’s Gross Production Tax taketh away.”
The way the math works out; you don’t pay about 5% (or so) of your gross to the Feds (about 1/3 of the 15% Depletion allowance), but the State’s 7% Gross Producion Tax pretty much wipes that out anyway. Net result = the State ends up with your “subsidy” (or most of it).
I didn’t read the “Study”, but I doubt if they bothered to look at the claw-back at the state level. LOL ... They never do.
