What a sordid mess that whole situation is. It's also readily apparent that many people commenting have no understanding of how business processes actually work in the real world.
Because like it or not, those execs - while they may have contributed to the downfall of the company - are the ones who know how things work inside the company and where the bodies are buried. Them leaving destroys a lot of the value of the company in a liquidation or restructuring, costing creditors (including the workers in the form of pensions) a lot more than the amount spent in bonuses to retain the execs. That's why judges in bankruptcy proceedings often OK huge bonuses for execs, even if those execs are the idiots that messed things up to begin with. Having them all bail out is a lot more costly in the grand scheme.
In addition, if you add up all the exec bonuses and salaries, it doesn't add up to a hill of beans compared to the total company numbers. It's a nice hot button to get people mad, but in reality executive bonuses are meaningless in terms of the overall cost structure and don't have anything to do with the survival of the company.
That said, I feel bad for all those who through no fault of their own are now getting screwed out of a pension
