There was a "boom" like this in the UK about ten years ago, instructor shortages, pilot shortages. Muggins here went and got her BCPL, AFI etc, then watched in dismay as airlines went broke and unemployed ATPLs came looking for instructor jobs. It's a very cyclic industry. Hope it never gets that bad again for everyone's sake.
Meanwhile my advice would be to never put all your eggs in the flying basket.
