Could start IMHO by heavily taxing air travel. In particular short haul. Seems to me idiotic on every level that you can fly by air for a couple of hours to a european destination for twenty or thirty quid. I mean we all love to do it, but at the same time isn't it a little bit insane?
Taken to its extreme you could make the case for legalising heroin and taxing it at a level that would benefit the public coffers. Would that ever make it right tho? Of course not
Public health should win the day over any pro-smoking economic arguments. Ditto over any pro-car economic arguments. Both sets of lobbyists make a strong case. Doesn't make either case right tho
