Oil companies aren’t going to subsidize politicians to the tune of tens of billions of dollars.
Your conclusion that because we export, we have no dependence on global supplies is nonsense, unless we reinstitute the Energy Policy and Conservation Act of 1975 which Congress repealed in 2015 as fracked shale crude began to flood the market.
If we can get along without foreign oil we should. I recall one chain of gas stations always having lower prices than the others. A fuel trucker pumping gas into one told me they got all their fuel from Venezuela (pre-screwed up Venezuela).
If the price was lower even with the added cost of shipment that tells me America’s being gouged for the sake of sheer greed - as standard business policy. I stand on my statement that those companies, if they had good sense and any love for the country, would throttle that greed back for a few months.
I know it will be a hardship for some executives to settle for a lesser sports car, but sacrifices have to be made.
