Just wait until he starts hiring people. He'll need those people who are satisfied when their work life is 'mediocre' by his terms.

I think this is the best point brought up so far. He doesnt realize that others have different ideas about what success in life is. You cant be at the top looking down on your employees as just people who work for you and who are happy with mediocrity. It's a team effort, some have more responsibility than others.
