I'm not saying that anything will or will not happen, but I remember just before Air Europe folded (many moons and buffalo ago) that you couldn't get on a flying course at any of the major schools for at least 4 years. Afterwards, of course it all vanished overnight. I think there were just 2 jobs in Flight that week, so it can happen.
However, it is true that we are now a service-based economy with not much in the way of heavy industry (or gold) to back it up and it is very fragile indeed. That's partly why there are wars, to keep the money circulating.
If you have a dream, carry on with it - what else are you going to do? The problem with this industry is that you have to think at least a year ahead, and all you have is your gut instinct.
Good luck whatever you do
