21. Charles Wang

The former CEO of Computer Associates has continued to prove he loves LI, sometimes not making friends in the process, though. Wang has been lobbying hard for the land around the Nassau Coliseum to be developed and his planned construction in Plainview-Old Bethpage has ruffled feathers at every turn, so much so that his plans have been scaled back considerably and he is back to the drawing board. Wang has long been a true power player, so it is no surprise that he remains high on the list.
