Depends in what manner you're speaking. Bruce mostly doesn't run his company at all. He leaves that to people. Lex makes his companies thrive with his own hands. Bruce was handed his company and position mostly, Lex has lost and rebuilt empires. One day he's fallen from the heights, disgraced by the public, humiliated, his named ruined, his fortune gone... next day, he's richer than Bruce again. And everyone loves his new shit. He's a trendsetter.
