Actually, many MediCARE beneficiaries are also on MediCAID. It’s a common tactic to apply for MediCAID to cover long-term skilled nursing facility charges, aka nursing homes, because MediCARE has a strict limit on SNF.
The topic is very complex but one thing is simple fourth grade math: people do NOT pay enough in taxes over their working years to match the claims submitted for their care on MediCARE.
Additionally, you can thank Obamacare for killing the Medicare Advantage program. Look it up.
And how much you wanna bet that Medicare, Medicaid, and Obamacare will morph into one gigantic monster. Obamacare is destined to run short funds and guess which funds have “extra” money “just sitting around.” The politicians have been pilfering Medicare all along. Why not use Medicare and Medicaid to cover Obamacare's shortages and visa versa — sort of a shell game.
