I'll assume you're saying there are drugs sold here and nowhere else, because that would be relevant.
I merely gave an example that US manufactured drugs still have exorbitant prices.
Insulin for example is not imported. And there is not a lot of innovation to be had in that sector either. They just price gouge US customers because they can.
Therefore the "favoured nation" status that Trump wants to enforce does nothing. Because there are often no other nations involved. Again: Insulin is the best example here. It's not like the US exports that stuff.
The whole market is contained to the US. From manufacturing to distribution.
So what is Trump going to do? Make pharmacies stop buying Insulin from their suppliers, because other people around the globe who have no connection to your market whatsoever have figured out a better way to do it?
It's been commonly said for a long time that American prices are to cover R&D costs.
Now you could say that's wrong, the R&D claim is a complete scam
It is not a complete scam. But mostly.
R&D is a nice excuse to price gouge.
But as previously shown in other nations also conduct their own R&D for a fraction of the cost.
As a whole, the EU contributes more to medical research than US drug manufacturers. And our prices did not explode like yours.
Sure, R&D plays a role in pricing. But not anywhere to the extend that US drug manufacturers would want you to believe.
A lot of R&D also happens to improve on drugs that already exist and have established applications. Sure, better drugs are great. But what is being researched often has VERY niche applications so they can price gouge harder. Not so they can improve the actual quality of lives.
For example anesthetics for eye surgeries that work slightly faster than the "old" anesthetic used, so the Surgeon wastes less time on preparing the patient.
That is cool and all, but in no way life saving.
