After Carlos Ghosn's shocking arrest Monday, many of his most ardent supporters were left to reconcile their positive image of the man said to have saved Nissan Motor Co. against the possibility he may have committed numerous crimes.

But over the next few days, as details of the case emerged, the scandal appears to be less an aberration and more a replay of the one thorny issue on which Ghosn often tussled with shareholders, the media, and his own employees: Can greed be good?

Despite being regarded as the man who brought back Nissan from the brink of extinction, Ghosn has for years faced skepticism amongst the Japanese public over whether he, or any company head for that matter, was worth a massive paycheck.
