Mark Carney, the newly appointed governor of the Bank of England, will be paid about £1 million a year, all in. That cannot be the right amount. It is either way too much or way too little.

This would make Mr. Carney's job dead easy. He need only get some diligent secondary-school children to plug the relevant economic data into a computer model that embodies this scientific knowledge, then vary input interest rates and see which one will deliver the British government's 2% inflation target.
Anyone who can read numbers from a computer screen could do the job. Mr. Carney should be paid no more than minimum wage for the few minutes it would take him to do it each month. He should earn no more than £50 a year.
