I don’t believe in any kind of government health care, but if a person asks for social welfare benefits, whether they be Medicare or Medicaid benefits, then they should be prepared to make the changes required to reduce the cost to taxpayers. If we would just agree to get the government out of health care, period, these kind of problems would not arise.
What you say would be true only if individuals had the option of opting out of the system entirely, including the payment of the portion of taxes that support the system. Since payment isn't conditioned on any of this stuff, nor can you choose to opt out COMPLETELY, neither can benefits be.
