I think that House's representation of healthcare is the total opposite of what happens. That is to say healthcare practitioners are not as vigilant in determining the cause of illness or disease at all cost. They are more concerned with malpractice issues and whether or not the patient is able to pay.
In the real world doctors do not risk their careers to find the truth and are more compliant with hospital policies.
House is fantasy of what we envision the practice could be but in reality we would not tolerate such an obnoxious doctor treating us. No one would be willing to work with House.
