his business credentials are vague to say the least
He’s filed for bankruptcy 4 times, hardly a glowing track record of responsible long term administration.
Yep, and whilst he’s very wealthy – it’s widely accepted that he’d be wealthier still, if only he’d taken the vast amount of money he inherited, stuck it in the bank and lived the playboy life. His decades of being a ‘Business Mogul’ has cost him a lot of money.
(in regards to bankruptcy, he’s never been made bankrupt personally, he asset striped and bankrupted 4 of his corporations – arguably they were viable businesses, but it was more profitable to close them and leave his creditors and the IRS to pick over the bones).
