If you're in the training pipeline, I think it comes down to two scenarios...
1. If you can stop spending money on training AND still have or can still get gainful non-aviation employment, it might make sense to take a break, hold on to your cash, and give it some time.
2. If your training money is already committed, and/or you have no job, might as well continue with training as able.
There is a potential silver lining... if things don't turn into a great depression, there will still be retirements and a lot of new entrants might be scared away. When the dust settles, that could leave you in catbird seat if you stick with it. That's a possibility but nobody knows for sure.
