> I'd be fired if I caused enough loss in revenue to pay my own salary for a year.

I'm not so sure.

I know of a major company that had a glitch, multiple times, that caused them to lose about ~15 million dollars at least once (a non-prod test hit prod because of a poorly designed too).

I was told the decision-makers decided not to fix the problem (the risk of losing more money again) because the "money had already been lost."
