Lewis continued: “A carbon tax was never meant to be a revenue source, but to change behavior, to stop the use of coal, oil and natural gas.”
His point: Tax carbon, consumers can’t afford it, use goes down. But revenue goes down, too — so the feds raise the tax to fill the gap. Use goes down again, revenue goes down again and the tax goes up again. It’s like the mythical dragon swallowing its own tail, only instead of a dragon it’s our only economically practical energy source.
