This is incorrect and a giant red herring. Pharma is not "raising prices" in the implied sense, and pharma is not the cause of drug prices being high in the US.

Pharma is increasing the "gross price" of a drug in order to increase the rebate going to the PBM (Pharmacy Benefit Manager) so that they maintain their position on the formulary (to be "covered by insurance"). The "net price" of drugs (what pharma makes) is overall growing at the pace of inflation, not above. There's obviously exception cases, and plenty of small biotech firms launch questionable products with high prices that then get covered. But this is a result of this rebate system that prioritizes covering drugs with large rebates (since PBMs monetize rebates), not the most cost effective drug.
