For a minute I thought the high bidder was Fidel Castro ... this other ‘Cuban’ is just as bad.
He really isn't. He is just someone that got a bit lucky in life (but bear in mind that he MADE that luck with a lot of personal effort) and doesn't always realize the consequences of investments. He is no more (or perhaps no less) a villain than someone who has bought shares in Philip Morris.
There is a lot about Mark Cuban that doesn't get mentioned on the news that if you knew about might change your mind. Talk to the families of some of those wounded or killed in Iraq (or just do a search for "Fallen Patriot fund") and you'll probably change your opinion of the man.
Mark Cuban is a Texan by choice. That alone says something about the man.
