This really isn't an unusual story of business failure, TBH. They took out loans to cover their operating expenses in the hopes of generating better revenue in the future, using their tangible assets as collateral. They had to take out loans or else the business fails; with the loans, there's the chance that things could work out. Dixie Carter's personal assets are largely protected, unless her and every financial advisor around her and her family are literally ******ed, so the creditors fight over what they can get a hold of, and the worst thing that happens is a bunch of other people get put out of work.
Of course this follows from the idea that Dixie Carter's goal for TNA was to maintain operation of it. I long ago gave up thinking that Dixie Carter's primary goal with TNA was to generate a profit for ownership, because the smart thing to do would have been to sell the company two or three years ago when they still had a strong potential upside.
As far as the intelligence of some of the creative decisions TNA has made over the years and how that reflected on their business, that's another story.
Kinda makes you thankful WCW died overnight, huh?
