The problem--too many healthcare dollars spent on costs which are not medically necessary

The United States healthcare dollar is paying the salaries of many people who are not directly involved in providing healthcare. Some examples:
• Creators and publishers of direct-to-consumer print and live media advertising for prescription medications.
• Creators and publishers of advertising for professional and institutional providers of healthcare.
• Employees of insurance companies (medical, auto, workers compensation) which cover healthcare.
• Creators and publishers of advertising for healthcare insurance companies.
• Insurance brokers who sell insurance which covers healthcare.
• Employees of companies which process healthcare claims.
• Personnel department employees who handle group insurance enrollment for employers who provide health insurance.
• Employees of hospitals, pharmacies, medical equipment companies, physicians, and other healthcare providers whose jobs are to submit claims to insurers and communicate with insurers regarding eligibility verification and prior authorizations.

An efficient healthcare system could eliminate most of these jobs, at the price of increased unemployment.
