By why would someone work for $150m when they can get $250m? The pool of CEOs that can successfully run billion dollar companies is pretty tiny.

The question isn't whether someone would work for $250m but would not work for $150m; the question is whether someone would or wouldn't work for you for that amount. If someone else offers $200m to the same person, they would work for you for $250m and wouldn't work for you for $150m.

Mr Buffett is 92 years old and works every day and is worth approx $120 billion.

In the past 70 years hes had more money than needed for him to decide to give it all up. Why hasn't he?
