there is a great example of this in medicare reimbursements. i dont recall the details, but the gist is that there were 2 types of eye surgeries. #1 had high reimbursement rate to doctors from medicare. #2 has low reimbursement rates and was considered extremely dangerous by the medical community. for whatever reason the law was changed; the reimbursement was flipped from surgery #1 to surgery #2. immediately #2 became safe and preferred and #1 became dangerous. hundreds of these examples in medicine. anytime someone tells you that doctors are above money, it’s complete bullshit.
