My 2 cents.....
Yes, there are those 19-20 year olds out there who will happily do many of the jobs here at $9-10 per hour. Single, no cares, happy to live paycheck to paycheck. That said:
1) what do you do with the 45-50 year olds doing that job here now? Furloughs seem to be coming, so there's no empty positions for those youngsters to fill. So the answer seems to be reduce the wages of these older career employees to $11-13 per hour (after all, there's people out there that will do it for less). That brings us to ...
2) now you have to tell those 19-20 year old prospective employees that they can have a wonderful career in aviation - nonreving to exotic locales, etc - and in 20-25 years they'll be making a whopping $13 an hour. And by the way, since you're the new kid on the block, you'll be working Christmas day, New Years Eve, etc. in the heat, the cold, the rain, the snow. That pool of prospective employees starts to get a little smaller.
3) then their friend tells them that WN, B6, etc are hiring - and while the starting pay might be the same, in 10 years they'll be making 3X as much. Besides, those other airlines are growing - might have to work New Years this year, but not next. And you should see what goes on at the company sponsored annual party, man, far out. That pool of prospective employees gets smaller still.
