I assure you that I had no special skills when I moved out of the US the first time 🙂 I was a decent but otherwise run-of-the-mill junior software engineer. The only "special" skill I had was being rather good at coding tight assembly - something that was in demand when embedded systems didn't have gigabytes of disk and RAM and processors that would rival a Cray-I just to flush a toilet or something.
I picked up skills that are quite valuable along the way (I am certified aero QA engineer on the white collar side, and I have a degree in a rather obscure but highly-specialized metalworking sub-field that I shan't mention because there are so few people working that field on the blue collar side). So it helped to find new jobs for sure.
But the relocating and moving countries was just me wanting to see the world before I was old by living where other people lived for real instead of being a crass tourist for a week, and it didn't have much to do with my professional qualifications.
Everything Trump and his henchmen do seems to have a degree of built-in cruelty. Kilmar Abrego Garcia, being one of the few real thorns in Trump's backside, probably earned himself an extra helping or two.
