Highest grossing 'Supporting' Actor of all time...

In my opinion Samuel L. Jackson just does not deserve to be in the same list of highest grossing actors as say Harrison Ford or Eddie Murphy. Both of those guys have spent the majority of their careers as the lead or one of the leads in the movies they made. However, Mr. Jackson has spent the majority of his career in supporting roles. I mean he still gets the same amount of credit as someone like an Eddie Murphy, but he only works half as much in each movie(or at least the ones where he's the supporting actor). So I think they should make a separate category for supporting actors. I welcome other peoples opinion on this subject. What do you guys think? (P.S. I will ignore and delete all trolls)
