Rights and Benefits

Ezra Klein:

Access to health care should not be dependent on the kindness of your employer.

And being employed shouldn't be the exclusive passport to, you know, not dying. But if it is, then why aren't lesser concerns like speech, religion, assembly and habeas corpus considered "benefits" of employment, rather than unalienable human rights? Put another way, petitioning the government is considered a constitutional right, but medicine is considered a marketable commodity. America is weird.
