They don't pay tax

It looks as though sound political thinking may be more widespread than I had suspected. This letter from D R Mayer concludes:

By the way, as all pay for the public sector comes from the taxes payable by the private sector, it is possible to argue that the public sector does not contribute to the tax take: it only consumes it!

Mr Mayer is correct. No one working for the public sector, nor any of its beneficiaries, pays any tax whatsoever.
