I don't think that retirement benefits are the issue here. The issue is socialized medicine, where those who have NO health care benefits, due to personal non-purchase and/or jobs that don't include benefits, getting health care benfits from a socialized state (where taxpayers are forced to fund medical coverage for others).
The illegal aliens, for example, pay nothing for medical insurance, and just show up at the emergency rooms and the non-paying service is recovered through increased medical insurance premiums to OTHERS to offset the cost, and/or through TAXPAYERS who will be subsidizing services to non-payers in a socialized medicine scheme.
