Nope. But again, a lot of other economic activities (housing, farming, etc) occur with some form of "subsidy," tax credit, write off, or other form of government incentive.
If the "playing field" were to be completely levelled 100% with no industry getting ANY type of support or incentive, fine, but that's not likely.
So, we should add one more industry to the uneconomic subsidy list? Just because you think it's cool?
