Elucidate please on your involuntary exchange forced on the citizenry paying for the services. Governments ostensibly acting from will of legislatures negotiate contracts with nurses, doctors, teachers etc and on breakdown often force them back to work if in essential services, usually with strong public support.

No one here says public workers are sacrificing their lives for anything, and those receiving higher compensation than the private sector get it the same way others do: numbers, organizing skills, political influence, appreciation for services.
