If someone decides of their own volition to become a slave, is that not their free will?

Most of us believe that certain rights should be inalienable.

Sometimes, perhaps, but not always.

But we’re not talking about someone advocating slavery, we’re talking about US politics, which is essentially a slow motion hysterical melodrama over whether to spend 30% or 40% of GDP on social welfare, and on which programs.

I'd say the democratic minority might disagree but since you defined it as being democratic it's impossible to argue.
