Again, you have absolutely no clue what you're talking about.
My wife works at a large hospital, which provides free care to people under 400 percent of the poverty level who are uninsured and somehow ineligible for any of the huge government medical care programs that already exist.
Free. Period.
There are no bill collectors or confiscated wages. None.
I would link to the paperwork here, but it has the hospital name on it.
If you had the slightest interest in actually knowing facts, you could do research on this yourself.
