It’s already normal and has been for a long time. Defeatist? No, people who have mortgages to pay and families to feed can’t be martyrs for workers’ rights. You want to change it, I’m not opposed, but you make it sound simple/easy.
Continually acknowledging it renews its legitimacy as the status quo. Who said anything about families or mortgages? The tech industry has plenty of single mobile renters; we can make change by having a little faith in each other.
The first step is for you to get your head out of the sand and look around. Jobs are scarce unless you're knee-deep in ML/AI. You're talking like a naive, idealistic, young person. I'm long past any of those attributes and I do have a family and a mortgage. Sure you can move to Europe, workers have more rights...and they earn a hell of a lot less than we do here in the USA (my brother lives in Europe.) And even there companies try to employ contract workers so they have more "flexibility".
HN is known for its optimism and abundance mindset. Aside from that, being group actions, reform hinges on mobilizing those who are able to do so to help those who are not. The phrase “solidarity” comes to mind, and that was the whole point. We need a solidarity mindset, not a sarcastic “good luck with that” mindset.
