Well, it’s the same here for the existing healthcare system in the US. Even basic reforms (obamacare) get met with insane opposition.
In the UK, it's from the voters.
In the US, it's from the Healthcare Industry.
They are allowed to spend as much as they want for votes due to their freedom of speech. Sure they can't directly vote but ever since like 2010 have a lot of human rights and I'm sure would love more. I would not be surprised if one day they could directly vote considering due to their rights. I hope though we can push back before then and change things.
