Instead, punishment for ALL crime should be proportional to the perpetrator's annual income. That's how they do it in Finland (and it seems also some ~~other~~ Scandinavian countries), for instance. They have had at least a couple of instances of over $100k speeding tickets, for example. This makes incredibly SOOOO much sense that it will never happen in most capitalist countries.
