That's the thing, there's a day after today and a day after tomorrow. Right now, there's a shortage of ANY good jobs in ANY industry. Even IT guys who were first thought to be recession-proof are being made redundant en masse.
But what do we do when things pick up? Skilled personnel will be needed again. And in large numbers. In the context of aviation, even if we assume that recovery to 2019 levels and further growth will not happen until 2024, there will still be a lot of retirements in that period, hence a need for someone to replace those people. Not to mention that some pilots who are still far from retirement age are walking away voluntarily - and someone will have to replace them as well. There might be loads of wannabes out there, but you can't run an airline on 200-hour cadets only.
