Earlier quoted context omitted.
I'm fine with Exxon benefitting from a carbon tax. They have the political clout to push a bill like this through Congress, and it benefits the country as a whole to have carbon legislation in place. Seems like a win-win to me.
If a corporation, especially a multi-national, benefits from a tax, I would question the benefit to society from that tax. Not to say that society would not benefit, but it does make me wonder.
And in popular culture, if we end up with people opposed to a carbon tax just because Exxon wants a carbon tax too, well it doesn't more nose-less than that.
