Certainly unrestrained resource extraction and financialization of the entire economy- generating wealth for a select few with complex financial instruments that has no real purpose for the general public- are bad. But surely much of tech does provide some benefit to society. What happened to software is eating the world?
I'm not sure what you're referring to exactly. I'm not praising Google in this story- I think they're doing this strictly for business reasons- but I still think it's a positive action even if it's motivated by the bottom line. But it's inevitable that them, just like most other giant companies in the black, are going to expand sooner or later, and they will need more workers. So there's not much you can do about that. If it's not Google or Apple hiring, it's going to be Tesla or SpaceX or Kiva or these guys (https://www.nytimes.com/2017/08/16/technology/a-start-up-sug...)
My main point is trying to stem the demand for more workers, whether H1Bs or American citizens, is futile. And even if somehow American firms stopped demanding more tech workers, firms abroad will be as well. So why not try to train more people to become workers?
I never understood growth for the sake of growth mentality. Isn't that what's killing the planet, broadly speaking?
