If one has a government-guaranteed taxpayer-funded health care, that requires someone else (a taxpayer) to surrender a portion of their own wealth, their own property, to pay for it. That means that the taxpayer is required to labor for a portion of the year with no recompense.
There are several words for that; indenture is probably the most polite one.
