Twenty or thirty years ago if there had been a controversy about food or medicine safety, the political split would have broadly been:
◀️the left saying "big business is bad, look at all this shit they're adding to food and the unsafe medicines they're shipping, purely to make their life easier/cut costs/make more profit. Corporate greed at the expense of the little people, government must regulate"
and
➡️the right saying "big business is good, people can choose flour with folic acid in it if they want, and can choose to get a vaccine if they want, or they can choose not to, not up to the state to intervene"
But since the regulators, big business and government all merged into one large, single organisation, pushing a broadly leftwing globalist agenda, the left are now completely fine with the kinds of behaviour and people they'd have hated 20 years ago, and it's now, in general, people on the right complaining about food and medicine safety.
