There will be no pilot shortage in the next decade or more. Market is supersaturated with pilots and even if half of us leave the industry to work as delivery boys it doesn't mean we quit forever. As soon as opportunity arise we'r ready to jump back in. Rating won't permanently expire unless u keep it expired for more than 3 years and many of us will pay to keep it alive.
It's gonna be a tough year with little flying and little money and even though i believe that covid trend will become obsolete and forgotten by next summer , aviation is still facing a real 'great depression' scale crisis that will come in about 10-15 years from now.
I am still employed but willing to fly for food and mortgage just to keep me and my company alive.
