1) The largest private insurers in the US cover more people than many single payer countries, like Canada for example. They don’t get better prices.
2) As someone who works in the drug industry, Trump is actually the first President in recent history that is freaking out the pharma companies. His “international price referencing” proposal is being taken very seriously as it would have very negative consequences.
Private insurers aren't motivated to do any of this because high drug prices don't hurt their bottom line.
Insurers who say “no” (Aetna) is a good example, quickly lose customers to insurers who say “yes”.
He’ll, even Medicaid and Medicare at home flack for not having a drug on their formulary.
Very unlike other countries.
I don’t think they really care about prices as long as they can pass them on through higher premiums.
Dealing with a nation's major provider is very different to insurance companies. As I said, if you try to price gouge then they governing body will take what they need as a matter of national security/public health safety.
