In Naked Economics, Charles Wheelan writes about how important human capital is:
"... I once interviewed Robert Solow... I asked if it bothered him that he received less money for winning the Nobel Prize than Roger Clemens, who was pitching for the Red Sox at the time, earned in a single season. 'No', Solow Said. 'There are a lot of good economists, but there is only one Roger Clemens.' That is how economists think..." pp.100.
