Science is "easy" because we can model it, to a degree.
Non-science is so hard that we can't even model it, it's that complicated. So instead we try to voodoo our way around it, rely on simple heuristics, history, etc.
But the man who invented 1-800-GOT-JUNK and plastered the phone number on the side of every one of his bins was not some better of Richard Feynman. He understood one thing really well: If you solve a problem, have simple messaging, and unabashedly self-promote you will win.
The lawyers, and accountants, and technologists, will all come and help you with the complicated stuff in exchange for a piece of that mountain of cash.
I think one has to differentiate between "complex" and "complicated". Complex stuff requires Big Brains. Business is not complex, all its processes are simple and fairly well-understood; but it is complicated by the interaction of so many factors.
If you look at things that are actually hard, nobody keeps you from getting the info. You're just not going to understand that graduate seminar in ergodic theory, though you're welcome to attend.
The reason they keep you from the info is of course you'll see the naked emperor.
