With single payer, the government suddenly holds a lot of cards even without explicitly making laws. Most drugs have alternatives. Facing the threat of having all drugs that have sufficiently good alternatives disappear off the approved prescription lists makes most pharmaceutical companies quite reasonable to negotiate with even for players like the UK government that "only" represents 60 million people.

So get those costs under control, it's not like you need profiteers like your boy Shkreli profiteering off this stuff. Also ban drug marketing while you are at it. They spend half that money on marketing the drugs to consumers.

But then we'd miss the entertaining statements, like:

“Do not take Stelara if you are allergic to Stelara or any of its ingredients.” (Duh?) - https://www.youtube.com/watch?v=5ZzRAGeXtgU
