Have you tried accepting less than 200k? Sub 100k maybe. Works for me (at 40+). And then just work several clients as contractor. Beats flipping burgers, comes out at more than 200k.
AI still can’t fake a 50$ background check and verifiable references from past employers or clients you worked for. So I wouldn’t worry about juniors masquerading as seniors. Doing due diligence now is more important than ever.
