Lots of people sacrifice. That people don’t romanticize the guys going on boats to fish for months in the freezing ocean or go work at oil fields is another thing.
No one is saying doctors as a whole are the problem. They however are not immune to markets and failure in the business world should they try to start their own practice.
Health care is just another market good. No need to get in our feelings. If red tape is an issue for some doctors in some jurisdictions then they should react accordingly and that will create the necessary political pressure to change the regulatory environment that caused the problem.
