Do you know how much it costs to maintain and operate an imagining (MRI, X-Ray, etc.) machine? Do you know how much it costs to maintain staff (doctors, techs, office assistants, etc.)
As someone that used to think the same way as you, and then got to see other side of the business (my wife is a Veterinarian who runs an urgent care facility) —— it’s easy to think the way you do without seeing the costs incurred on the other side.
