“Whoa we can do this cheaper in another country???” is not a new phenomenon. Companies have been trying to do this for literally decades at this point. The reason so many jobs still exist in the US is because it doesn’t end up working that well. I’m not _that_ old and I was around at IBM for two separate rounds of “outsource-it-to-India-no-wait-bring-it-back” and IBM was and still is very keen to ship everything overseas.
I’m not saying it won’t eventually stick, but I think it’s important to dispel this notion that WFH made everyone have this sudden epiphany that US workers aren’t necessary anymore. It’s been going on for ages.
