You do know that countries other than USA have pharmaceutical industries. The UK should be able to shop around for the best deal possible.
You dear old sweet thing you. When we are dealing with the USA they are very, very big and have a great deal of clout. They will say to us that if we want to sell into the US without Trump's tariffs we will have to offer a quid pro quo. Trump is very fond of these. You may have heard.
In the recently revealed papers which, I imagine, like all other things you don't like you are trying to ignore, we learned that US officials repeated Trump’s concerns that countries like Britain aren’t "paying enough for our medicines", with a special concern about cutting edge biological medicines used in the treatment of many cancers. Introducing a US-style pricing regime would make such drugs unaffordable to the NHS.
You may have heard if you weren't burying your head in the sand, that our trade negotiators received special lobbying from pharmaceutical corporations as part of these trade talks.
On our own, we will simply be too small to deny Trump what he wants. The idea that we can simply walk away from trying to deal with him is for the birds and, as we have already treated our closed friends and allies like s**t they wont want to do good deals with us either. What will happen GG13 when we can't say no to the US, or China, or India.
Now I know you and some of your bitter little friends will tell us you know more than the experts, but I simply don't believe you. Usually, the next resort is a personal attack or childish rudeness. However, all our futures depend on everyone opening their minds to the real possibility that, although a very few people will get very rich the rest of us will suffer for decades to come.
