It's worth noting that subreddit in particular is populated by a lot of people who seem to have been told that dispatch was an easy way to make $100k without a college degree and are now extremely salty that they missed the brief wave where that was true. Everything I heard and read made sure to clarify that the post-Covid situation was unique historically, and likely would end soon... but some people didn't get the message, it seems.
And let's remember that the current abrupt slowdown is primarily due to both major aircraft manufacturers having significant issues; Boeing with... well, everything, but especially the 737 MAX program; and Airbus with the A320neo's P&W engines. When those start getting fixed, and planes start coming online en masse again, there will be another wave of hiring (provided we don't hit a recession, which none of us here are qualified to predict). There is still travel demand that the industry isn't able to fill. When the planes arrive to fill it, more bodies will be needed to make those planes fly.
Getting into a regional isn't sunshine and rainbows right now like it was even 12 months ago, and from what I'm hearing, you might have to wait a couple hiring cycles (applying to the same places, which shows you want to be there) if you don't have previous aviation experience and don't stand out in some other way. So long as you are accepting of that, and accepting of the risk that predicting the future is very imperfect, right now the long-term forecast is actually quite good for our industry, despite the current slowdown.
