There has to be a way for Medicare to pay for the medical needs of the people it covers. To allow for an opt-out would inhibit the ability for Medicare to pay the 80% of coverage. However, there needs to be a better way of determining amounts assessed to individuals. As it is, currently, a person receiving $800.00/month from Social Security has to pay the same amount into Medicare each month that a person receiving $2,500.00/month pays. Also, the amount taken out of a senior's Social Security check to pay for their Medicare is different from state to state; that is, a person receiving $1800.00 in Social Security and living in Illinois will pay a higher amount for Medicare than if that same person resided in Idaho.
