The "Could you do better?" is an point I don't accept. We pay others for their expertise and expect them to do a competent job. If a surgeon messes-up an operation we hold him to account even though the patient would have suffered a lot worse than the surgeon's botched job.Do you fancy the job of Chancellor of the Exchequer?
People criticise their favourite team's goalkeeper for a bad match despite that they could never have stopped anything in the same position.
Same with Chancellor, it is reasonable to expect competency even though one might not be able to do the same. In a similar way I can do some things better than any of our Chancellors.
Nature of specialisation and reasonable expectations.
