Medicare is a federal plan for aged people. Many times aged people will buy supplementary plan from private insurance company besides public plan. Doctors actually prefer Medicare over Medicaid, which is the federal plan for poor.

People who use Medicaid will never purchase supplementary insurance. They can\'t afford. Medicaid is under-funded and mismanaged. Doctors in general hate it.

If US has to go socialism on health care, please do Medicare, NEVER Medicaid.
