Stop the idea that you can pay to do something that is bad for the rest of the world, allowing rich entitled people to behave like arseholes as long as they throw some cash at it, just allows them to feel more entitled and smug and behave even more like arseholes. If flying around the place in private jets is bad, just ban them, if a car doing 11mpg is bad, ban them too, don’t just tax or fine them, get rid of them. You just make behaving like an arsehole aspirational otherwise.
