Privatisation vs Nationalisation.

What criteria do you believe decides whether something should be Privatised or Nationalised (or otherwise)? I have a few ideas, but to ensure no one is biased against the OP turning the thread into a flame war I will post as anonymous later once my IP rotates.

>For privatisation, the question is: can money be made from this in a way that will not degrade the quality of service?

The quality of service MUST rise because it's important to create demand for something since otherwise you wouldn't be able to make profit.
