What I want to point out is that if he was careful about his business partners, he'd be much better off now. It's not relevant why he wasn't.
He had the agency to mitigate the problem, and didn't. What happened was not an unpreventable natural disaster. The lesson out of this shouldn't be "you don't have agency so we need a safety net", but rather "we often have agency to stay afloat". Perhaps also "we need a safety net for when our bets don't pay off or when we don't".
