Man of Honour
I don't think the public should pay for clinical research, I believe in small government.
OK, that's consistent. I disagree on the appropriate size of government, but that's fine.
There is another issue, though. You specifically referenced Cancer Research UK as a private company ("private companies like cancer research UK"). Cancer Research UK is a charity and almost entirely funded by the public. It's private in the sense that it's not part of the government, but it's publically funded and it's not a for-profit drug development business. It has developed a number of drugs for cancer treatment that have then been sold for profit by drug companies. So public money is being used to benefit drug companies. Drug companies also use the results of publically funded research. So what we have now is drug companies profiting from publically funded drug development and other medical research. I think that's an inefficient and unethical way to go about medical research and drug development.
