Why isn't Wilt Chamberlain better then Michael Jordan?

Wilt, had the advantage of playing against lesser competition. There was no offensive 3 seconds, so he could just stand in the paint and shoot it over everyone. He was taller than everyone by at least half a foot. No one could touch him. If he played now he would be average at best. If Yao or Shaq played back then, they'd easily average 60 points a game. A string of Hall of Famers couldn't win a championship because they played in the same era as Jordan. John Stockton, Karl Malone, Patrick Ewing, and Charles Barkley.
