Lonhorn's assessment is logically correct.
The one thing I would not overlook however, is the power of skeletons, and also
the common comprehension failure as to what might constitute a skeleton.
The bigs are going have to be hiring a lot of folks. But that does not mean they will overlook ALL transgressions or throw standards out the window. They could find themselves hiring 85% of applicants, but I bet they will still be turning away at least a handful of folks. Keep in mind you might be one of them, and while I wouldn't plan my career around getting stuck, at least have a plan B in mind.
You could also see a "quantity over quality" revolution, ie they hire those with squeeky clean records regardless of experience as long as they have 1500 hours. This would probably bypass at least half of the experienced adult professionals who over the years have accumulated a little baggage in the natural course of things. We are already starting to see experiments of this nature.
