Unions might not be the best solution, or the most practical. I'm all ears for better ways to fight back against bogus leadership. How else can software developers advocate for their interests in an environment where their power is sharply declining (non performance based layoffs, "performance" based layoffs, reduction in junior hiring, reduction in in-office perks, reduction in total comp, etc)?

Arguably one motivation for Trump's tariffs is to onshore jobs. It's an incredibly brutish and stupid way to go about it, though. A much better way would have been to oppose NAFTA and similar global a marketplace policies, as Bernie Sanders has done for decades now (and has largely been in a pretty lonely position).
