Clearly stands to make far more money in the private sector. Making somewhat of an assumption here, but if that's his driver, then each to their own. Happy the man who can play a hobby to international standards!
I do recall andrew strauss being interviewed at the start of his England career and being asked if he is envious of uni friends who stand to make millions from working in the city while he gets by on a cricketers salary. His response was that he had the chance to write his name into sporting history and would rather be remembered for that than any amount of money in his bank account.
I always liked him after that!
