9/11 was an excuse for many unscrupulous companies/managers to do what they couldn't previously justify doing , i.e. to trample over everyone's conditions and reduce the workforce to the minimum, and then a little more besides.
This is no different really. Yes many companies have, and more will, go to the wall. It isn't just about losing money though, it's a god given opportunity for some sharp shooters to impose a " new order".
