[Carruthers]

A couple of points in the FWIW category.

(i) It came as something of a surprise to me that US exports are only marginally greater than those of the UK.
I assume that the huge domestic market eases the financial pain.

(ii) Switzerland's position was to be expected. There are only so many watches and cuckoo clocks you can export so the money machine that is the pharmaceutical industry is unlikely to fade away.
Decades ago, a Swiss firm* ended up in an almighty battle with the UK government over the rip off that they had perpetrated on the NHS.
My recollection is that they ended up paying back £400 million and this was in the seventies.

*Pretty sure that I remember the name of the company and the drugs that they overcharged for, but as there is scant evidence on the net to confirm my recollection, I'll leave them unnamed here.
