It's the cost. Of course this depends on the location and the type of nurse. I'm not in California, the most expensive place to get a nurse, where the average salary of a Registered Nurse is actually $102,700. Other states have salaries that are half of that. Even for the national average, a Licensed Practical Nurse is only getting $48,251. Allowing a factor of 2 for benefits and overhead, nurses generally cost about $100,000.
