When the dust settles do you mean when international travel returns? Because until then we won't get back to 2019 levels. I don't think there will be any shortfall of 1500 hour peeps to feed the regional machine for at least 24 months.
Flight schools in my area had a drop in students from March to July 2020 but have been back at normal levels since. That in my opinion has given supply a chance to "catch up" with demand so to speak.
I don't buy the pilot shortage apocalypse some people are predicting. Sounds like flight school marketing to me!
