He was an accountant
That's not really an answer. Like did he do peoples' taxes or did he work for Arthur Anderson or f'in what? I mean, come on folks - I don't mean you, I mean the idiot press who cannot ask decent relevant question - how about some details.
It's like saying Ted Koczynski was a math teacher. I mean I want to find a couple dozen so-called journalists and strangle them. All of them. Obviously there are none who are worth the salt in their own sweat, if they sweat, which I doubt since they certainly don't sweat the facts in their stories.
Yes he was - in the 80s.
At some point, he began investing in real estate and wound up making a fortune.
