You keep saying 'unethical' as if it's the end of the discussion. But what if our current standard of medical ethics prevent us from finding the better policies or the better treatments? Is this standard set in stone and never to be doubted?

Probably taking away insurance from people who have it as an experiment is too extreme, and not implementable anyway. But is it really that unethical to take a subset of population without insurance, give it to a random subset for some time, and observe the differences? Why? No one from the control group is prevented from getting insurance on their own (compare with the candidate drug trials, where the control group can't just buy the drug on their own).

No, it's not set in stone, but if you're talking about implementing studies now, you're not going to get major medical ethics reform first. You go with the system you have, and the system you have is probably going to push back pretty hard.

This alone is a difference between the control and treatment groups that takes place post randomization, and knocks said experiment back into the realm of "correlational"
