O&G companies are able to write off the cost of doing business just like other businesses. They are not "subsidies". https://www.forbes.com/sites/drillinginfo/2016/02/22/debunki...
It’s a ballsy move to compare the oil and gas industries to health. There is plenty to criticise about the way the US healthcare system is run, but do people really begrudge treating the two industries differently?
Letting companies deduct expenses like everyone else is not a subsidy.
It's like it's become part of the common mythos, that US oil companies get massive cash subsidies that are the sole reason they're not beaten by renewables, but the moment you apply any scrutiny it falls apart.
(Environmental concerns are legit, but the lack of better regulation is a non-standard usage of "subsidy" and people go further to claim that tax-deductions-everyone-gets are subsidies.)
