Your "business school 101" is really a high school class on keeping suckers happy. A good scam artist (let's leave the P word aside to avoid dumb word games) keeps the early adopters happy so the purse is nice and fat to handle the ups and downs of running a business that is legitimate on paper but exploitative and small-minded in practice.
This again? There are hundreds of examples of people doing very well without a college degree. Entrepreneurship isn't something that's learned in a class. You have to go out and earn your stripes. Some people have just got the knack. Is Josh one of them? The jury is still out, but he's started and sold off successful companies despite the naysayers here.
