Medicaid has income limits. The people getting Obamacare subsidies are those who made too much for Medicaid and too little to afford insurance on their own.
Every one else but seniors (covered by Medicare) will be allowed to buy the kind of health insurance, when they want it.

Income limits for Medicaid can be raised.
If we do away with Obamacare and its regulations that restrict competition and consumer choice, premiums should come down.
If we don’t do that, we’re headed for single payer within a decade.
