Difficult to say just yet as so many are still technically employed but not working.
Talking to collegues who are affected suggests that very few intend to head back to GA, certainly the entry level GA scene (I dont personally know of any). I think any lack of opportunity/progression at that end of town will be due to the fact there is nobody moving up to be replaced, rather than people shuffling back down.
I dont belive its pride stopping them, rather most airline guys/girls who have been made redundant are now a bit older and have estiblished lives in the major centres and for what they would get paid (certainly at the smaller end of GA) its not worth the upheaval of moving.
As with every bust there will be another boom greater than the last one, and within the next five years most who lost thier jobs and really want to stay flying will be back at it.
