This system doesn't work without complicit doctors. Unless those doctors are disciplined, it's basically condoning the practice.
It's easy to blame greed, and it should, but none of this works without the complicity of people who think nothing of spending 2 seconds to click and deny. They even have quotes from doctors saying how it was so easy to do it.
It wouldn't be easy to do this if there were consequences. And unless there are consequences, this is acceptable medically acceptable. I don't expect any consequences, to be honest.
