Okay, so -- just for giggles! -- let's suppose that emitting carbon dioxide really is a Bad Thing. (Quit exercising, people!) What I can't quite figure out is why, once our supervisors decide that something is Bad, they don't simply forbid it. Instead, they decide that the privilege of being allowed to do a Bad Thing is their property, and they sell us the privilege. Why, you'd think that our supervisors were uninterested in moral uplift, and instead are simply shaking us down, wouldn't you?
Oh, you say, but it's our government, so the money they take in is really our money, isn't it? And they'll spend it on us! Well, sure, as long as we want the right things ... and as long as we do what they tell us. Otherwise, goodbye, "federal" funds!
