Conventional wisdom holds that rich guys don't like to air their dirty laundry in public, which is likely why the descendants of H.L. Hunt settled their family feud on the courthouse steps in May. It's also why we relished the opportunity to view the dirty laundry filed by billionaire Ross Perot Jr. against billionaire Mark Cuban in the form of a civil case that alleged Cuban had racked up so much debt during the nine years he has been running the Dallas Mavericks ($270 million) that he had basically run the team into the ground. Perot claimed that Cuban's bad management had jeopardized the 5 percent minority interest Perot, through his Hillwood Properties, still retains in the Mavs. Claiming that the Mavs were nearly bankrupted by Mark Cuban seemed about as likely as saying that the Rangers weren't nearly bankrupted by Tom Hicks. Although Perot did his talking through lawyers, Cuban took his case to the Internet and e-mailed various press outlets, telling them that the lawsuit was an act of desperation on the part of Perot, who had lost big on his Victory Park development. No matter the right and wrong of it, the public was given a glimpse of rich guys getting all shitty with each other. And the prospect of watching how the rich play hardball remains as the lawsuit takes on age and animosity.
