They sure do know the "lingo", but they can't see beyond the next quarter and they never quite "got it" that a good businessman knows it's in his best interest to be honest.
My Harvard MBA brother-in-law can't understand how I can do real estate rehabs with contractors on a handshake. It's really not complicated, I use guys who know I will never cheat them and that if they cheat me I'll never use them again. Do you want the business 1x or for a lifetime?
MBA have a vested interest in things being complicated, other wise, who would need them? Ditto lawyers, politicians, academics....all those, ahem, productive types.
