Not enough. The US has a high break even pricer per barrel due to so much of our production being shale. There is a reason the Saudi's and OPEC manipulated the price down and Trump was correct every time he complained about them doing so as that reason was to squeeze out American production.
Don't get me wrong. I hate hight prices at the pump, but oil states need the revenue and American oil jobs are tied to profits, which require a high cost per barrel and in turn increases prices at the pump. Anyone arguing for low prices is inadvertently arguing to kill American oil jobs and against US oil production.
Of course, as high fuel prices effect many other things, those jobs come at a cost to othe sectors and if prices get too high it will drive a long term shift away from oil that will also hurt those jobs.
