I think you missed my point. If digging a hole for a swimming pool, it does not take one of great intellect to see it could be done quicker and cheaper by renting excavation equipment, rather than hiring a team of guys with shovels.WE are all subject to the Peter Principle. If I am smart enough and lazy, then I will likely find ways to do things the most efficeintly. If I am industrious and stupid, then I will do things as they have always been done, working longer and harder hours in order to get them done - no innovation there.
Twenty industrious but not too smart guys figured they would dig a hole and so they worked and worked mornng till dawn till the hole was dug.
The smart man, all by himself, hired a bucket tractor, filled it with fuel, had that very same hole dug in half the time and at half the cost.
But you seem to admire the 20 over the 1.
I don't.
I said that those who reached high levels weren't stupid, but the weren't the smartest guys on the planet either. And I don't mean that in a pejorative sense. They were average or slightly above average intelligence.
Obviously some level of sophistication is required to run a business. But one does not need to be an Einstein to do it.
