I don't see a reason they would be really against it. FDA says it to everyone, so all companies in same condition. And they can shift cost to healthcare system and have larger revenue. They probably don't mind their pie as a whole being larger, because having revenue of 50 billions and profit of 10 billions is better than revenue of 5 and profit of 1, even though proportionally it's the same. All big pharma companies are massively profitable, fx Novartis net income in 2017 $17.8bln on $50.4bln revenue. Pfizer's $14bln operating income on $53.6bln revenue in 2018. And it's year after year. They really don't seem to suffer from those high costs trials. Also, Pfizer reports only $8bln on R&D in same 2018. I'm sure there' a lot of inefficiencies in those trials, same as it turned out vaccine could be created in year instead of a decade. (btw, previous large scale epidemic of swine flu was largely profitable for pharma companies). They just don't have incentive to reduce the inefficiencies. You're telling it's not just US but then you cite high healthcare costs (retail vs large scale trial, definitely can be cheaper at scale), which is much cheaper outside of US. I would be very interested in reading numbers of detailed case study of creation of some real world vaccine/drug.
