Can you quantify "essentially put vacations out of reach of the middle class"? If flying cost twice as much, then people would, at the limit, be able to fly half as often as they do now. If they valued their vacation more than other stuff they could just do it anyway, assuming we're talking about the same "middle class" (e.g. not the poor that spend to their max). But yeah, the whole point is to reduce luxury travel. Jetset vacations are a luxury. We might be able to make them cheap and clean in the future, right now offsetting has a real cost.
