Edit: I've personally been taken advantage of by an Ivy B-schooler so the piranha thing is real. It was the typical thing you hear where I, an undergrad, had written a bunch of code with a verbal contract from the MBA student that I'd own 10-20% of the business. After a few weeks, when paperwork was being filed, I was informed that I'd get more like 1% to be the first engineer and finish building the MVP. It's not that MBAs are bad but a lot of the ones I've known have been indoctrinated into this way of thinking of creative people as resources to be harvested. It's not evil, it's approaching business like a game, knowing all the rules, and playing to win. It does look and feel evil when the rules are used against you before you know you're playing.
