Apparently the cost of research and development isn’t the cause.
Large drug companies simply can’t afford to keep spending as much as they are now, when about 10% to 20% of revenue goes to R&D
That’s 10-20% of drug company revenue, not including the markup your pharmacy and “health insurance” company add. I wonder how much of the remaining 80-90% is spent, directly or indirectly, on lobbying and enhancing their privileges.
