corporate and financial interests were completely disconnected from all our health care and pharmaceutical systems

This is not realistic in the slightest. Reasearch requires resources and the time and effort of highly qualified people.

It's extremely realistic, humanity makes the most progress when research does not need to create a monetary benefit. It allows us to explore ideas unabated. While these systems need funding we could take a 1% from military spending and invest with government resources. Hence why the mrna vaccines actually progressed so quickly, they were already being researched by the army for quick and rapid treatment of diseases during combat, i.e. just to solve the problem not just to profit from the tech, they lent that research out and gave grants to the corporations who developed and manufactured the covid vaccines. Internet, developed for combat communications not for profit. Most computer innovations came out of the space race, research without a profit motive. The ideas funded by corporate interests revolve around optimizing profit, not progress, which is why we get planned obsolescence, lack of rights to repair, massive healthcare costs needing insurance offsets, etc. I guarantee you can't name an actual positive innovation that was spurred purely for profit and not bastardized in the name of profit from a century old idea people forgot about so the company could attribute genius to its wealthy founders crud copy and paste job.
