Well, money would be the most obvious one, but the parent comment is talking about the anti-science regime currently in power in the USA. I can't remember which, but I thought I read they banned some effective treatments because RFK Jr (famous conspiracy theorist now in charge of the country's health) didn't believe in them. They shut down research into mRNA medicines. at least, because they think it's population control to keep you docile, or something like that. There was also a mass shooting at a CDC office on similar grounds.
