I mean, do you consider every tax deduction to be a subsidy? The standard deduction for all US families? Is paying anything less than 100% of income a subsidy?

The US government has a very established tax code to specifically determine what amount of money it should consider taxable and to smooth out expectations. Claiming a deduction is not inherently a subsidy. Especially if you are a business and might lose 3x as much money in a year as you make to invest in long term growth.

If Oil and Gas have unfair tax advantages, that's a problem. These seem boilerplate.
