I don't want to give too many details so as to avoid doxing myself. I never left the US and wouldn't have done so if asked, but fundamentally, I don't think that really matters. It's all part of the same machine. It was well before I became anything that could be described as communist, but all that means is that it hit that much harder when I had to come to terms with what I'd been a part of.
Maybe that's the sort of thing you can't ever make up for, but I'll spend the rest of my life trying anyway. If anyone on this site never wants anything to do with me again after having read this, I understand.
As someone in systems engineering, almost all jobs are fucking defense in all of the west. Everything else in engineering is outsourced to other countries through imperialism. It's why I'm doing train stuff. You gotta deal with companies that are in the top 10 evil companies of the world, but I avoid it as much as possible. The defense contractors even found ways to integrate working in the public transport sector to bring it under their umbrella. Sucks
