In the US, where pharma companies are still behemoths, they can divide et impera insurance companies, so pharma companies pretty much impose their prices, leading to absurd stuff like fancier insulin costing $1000.
Now, instead of working to reduce costs in the US, too, Trump & co want to INCREASE the cost of these drugs globally.
