Honestly I have never looked into his wealth building strategy. I imagine it had something to do with the hotties he had on his walls during his TV show. I mean come on what the heck tops that kind of status right? Funny stuff ;)
In all seriousness I have heard he has exceptional business acumen and is a ruthless negotiator. It doesn't surprise me because those boys are a dynasty all to themselves and will forever imo be remembered as an ageless past time. Talk about building something from nothing my god that would have been a train I'd happily have purchase a seat on....cargo?
