Because the biggest differences now are: remote collaboration tools are mature, companies learn to hire-and-replace one-by-one. So existing US-based staff was used to onboard new non-US members, then once those members ramped up, they were used for further onboarding newer non-US members. Then when the layoffs happened, most of the brunt fell on US based members. This didn't happen pre-covid where you had to replace the whole team, which was much harder to pull off. Also, tools (like Zoom) were not yet widely adopted and the populace wasn't trained on them. Covid forced us to learn all those tools.
