So do you have to be a god tier Nobel Laureates to get this kind of gig where you just learn about a business and then offer random suggestions that might or might not help them and charge obscene fees for the privilege?
I think the story sounds fake because they listened to him.
Having the ideas is easy. Persuading and organization to change is not.
Perhaps it’s a cultural difference between the middle of the 20th century and now.
Nope! There are consulting companies all over the place filled with bids and not filled with Nobel laureates!
Ergo...
You definitely don't have to be god tier anything, you just need to know at least a little more than the companies you are consulting for.
This kind of work has been my primary income for the last 4 years or so. Nowhere near on the same level as Feynman, but I know enough about enough other things that I get a lot of reputational referrals.
