The article doesn't address what I think are the main complaints about H-1B: that it is mostly used to cut costs and hire people who have very little freedom to switch jobs. That and all the trickery with ghost jobs meant to only give the appearance of hiring stateside. The example given is also not great. Von Braun was one remarkable foreign expert in a leadership position. On the other hand, in my experience, many H-1B hires tend to occupy low-level jobs; ironically the very ones that the author says will be filled by motivated Americans. I mean...just try working at any American FAANG. The evidence is totally in your face.
