I hate to break it to you but these high paid CEO's are not very good at creating wealth.
They are normal human beings except they are superior politicians and bullshitters.
They are not special in any other way.
Just because you don't understand what they do doesn't mean they don't produce value.
I've seen the difference between good management and bad management. It's like night vs day.
Management is something people can do themselves.
And yes, there will be groups that manage themselves better than others.
You still are imagining a world where all the employees understand all aspects of the job to a reasonable degree.
That is rarely reality.
