I.e. it's not about how hard or long one works. It's about working effectively.
Scenario A: "I want to make iPhones. All you people at Apple, and all you people at FoxConn, get to work."
Result: iPhones and wealth.
Scenario B: "I want to make iPhones. I wish I had some laborers."
Result: Nothing.
Scenario C: "We workers want to make something. Mr Jobs, we hire you as our manager. Get to work, and sell these things."
Result: maybe iPhones, maybe what we have today, maybe something else.
Ideas and management are great and necessary, but not sufficient and not exclusive.
