One of the things that has really struck me, Red, in the last few years, is the way Democrats, which is where American voters who tended to be anti-corporatist, and anti Big pharma were found, seem to have become firmly on the side of these things.
It's a bit like the way that the new political order seems to have firmly wedded the political left to globalism where previously tat is where you found anti-globalism. It's now, on the left, looked askance if you question the motivations of major pharmaceutical companies! I remember people being quite het up because of someone questioning whether companies were likely to release any research that suggested safety or efficacy concerns (which happens all the time!) or whether allowing them to avoid legal responsibility for damage caused by the vaccines was a good idea. Suddenly, it was like these companies were well known to be transparent and altruistic.
I know at least one person who I believe has completely changed her politics over this. My university roommate, who is American, grew up in a very crunchy household, her parents were hippies and they lived on a remote farm and grew most of their own food. She tended to be very into natural medicines and also joined the Democrat party when she moved back to the US after her degree.
Last time I saw her in person, toward the end of COVID, she told me that she was now a Republican - I don't think she was even torn about it. A very significant element of that was just how the Democrats in the US had gone completely nuts over COVID, and become (or wanted to become) completely authoritarian about health matters.
I also think that sometimes people in the UK don't realize that their own national response was relatively moderate. There are other places, including some in the US, that were pretty extreme about trying to impose things like vaccination requirements. Not always directly by the state, but by allowing or even encouraging private workplaces to require it.
So some of what we are seeing in the US now is very much a reaction to these kinds of things.
