I think you missed AC's point. Corporations don't pay taxes; people do. The corporation merely figures taxes as one of the costs of selling a product and rolls the cost of the taxes INTO the product that people then pay for.
It's a clever way for the government to divide and conquer because they way it is sold is that "Corporations don't pay their fair share!" and the people fall for this ruse and "demand" corporations be taxed more, loopholes cut, etc. So then the people pay more for the product still believing that the Corporation is getting a deal.
Good example: EVIL Big Oil Corporations and their "obscene" profits, which is less than 10% on a gallon of gas while the government makes over twice as much on the same gallon. That's what is funny about electric vehicles. Government is worried that they won't suck so much money in gas taxes as the market changes, so they now want electric vehicles to "pay their fair share!"
