According to the Policy Ed video, only 37% of Medicare expenditures are funded by payroll taxes. Per other sources, after Medicare beneficiary premiums (and other sources) are considered, the federal government still covers more than 55% of Medicare expenditures from general tax revenue. 

   

What does this mean in the sense of how much the federal government (i.e., tax payers) finances/subsidizes care for Medicare beneficiaries (as opposed to Medicare beneficiaries paying directly for care)?
