This fucking choad made his fortune by the sheer luck that Mattel didn't perform the diligence when they acquired his poorly managed education software company. The purchase pretty much doomed Mattel and the CEO who was terminated for it even agreed that her termination was justified.
But that's the case with O'Leary, Musk and Cuban: none of them actually created and grew profitable companies, they got rich on quick exits when their buyers were too stupid to look at what they were purchasing.
