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.
