As with most things, I'm fairly sure the truth lies somewhere in the middle and it varies industry to industry. Yea, a lot of stuff went to china, but a lot of workers were also replaced by automated systems. In a lot of cases, I'd even venture to say maybe a majority, it was both. It's not even close to factually true to say it's JUST china or JUST robots.

Also, do you mind elaborating on how that's specifically anti-worker? Either case can be construed as such depending on your position.
