It does seem to be a simple principle. If your product causes a social problem, you should incur extra costs to mitigate it. Same principle we're applying to climate change. Another good idea would be a sugar tax. You're selling sugary breakfast cereal? Yep, people do want it. But you're going to have to fund a lot of treatment for diabetes, sleep apnea, knee replacements etc. Gun manufacturers? How about some extra kick in for law enforcement and hospitals.

I can hear the screaming from my old neo-liberal self but I'm honestly not sure there's anything wrong with this.
