— Trump said in his inaugural address that the “liquid gold” of oil would make the nation wealthy as he pivoted the economy to fossil fuels. But the logging and mining sectors — which includes oil and natural gas — have shed 12,000 jobs since January. While gasoline prices are lower, the Energy Information Administration in August estimated that crude oil production, the source of the wealth promised by Trump, would fall next year by an average of 100,000 barrels a day.
