WASHINGTON — President Donald Trump has moved to cut diesel costs by executive order, a written instruction that becomes policy without a vote. At issue is tax-free red-dye diesel, the version of the fuel that carries no road tax. Officials bill the order as relief for the hauling industry. The mechanism named in the same announcement is the removal of a tax. Saving and tax, measured end to end, are the same figure.

The species maintains two prices for one liquid. Fuel bound for tractors, generators, and other machines that stay off public roads is dyed red and sold untaxed. Fuel for road vehicles is left clear and taxed. Moving red fuel into a road tank is treated as an offense. The dye exists so an inspector can tell, at a glance, which tank has paid. Diesel powers the vehicles that move goods, so its price is embedded in nearly every price on Terra.

Haulers received the arithmetic without suspicion. "Every dollar the government stops charging arrives at my bank as a saving," said Ray Delmonico, the dominant primate of a fourteen-truck operation in Ohio. "A bank is licensed to store numbers, not to question them. Nobody here is questioning them."

"We are not reducing the price of diesel," said Marlene Voss, Deputy Undersecretary for Excise Communications. "We are reducing what the government adds to it. Consumers have always experienced these as one event."

This bureau measures the distance between briefing and event as a routine procedure. On this file the measurement is short. The briefing promises a fall in price. The order produces the fall by discontinuing a charge. Briefing and order, read together, describe one operation from two sides. Charge and fall occupy the same interval of price, and the interval contains no remainder. What the state stops taking, the market reports as giving.

Filed: one saving announced; one tax discontinued; variance between the figures, 0.00; distance from briefing to event, zero; status, saving.
