For sure those jobs also bring much-needed foreign currency into the country that helps stablise the peso and drive spending as these call center staff spend their money in their local economies. If it dries up, that's a lot of US dollars leaving their local FX market too.

Indeed it will drive wealth concentration, even if they had access to markets, I don't think the person working those jobs or people who benefit downstream from that income now are going to be like oh well better get some Microsoft, Google, and NVIDIA stock to offset it if they can even afford to do it.

Transitions are always painful, and people will always get left behind, but markets do adapt, I have no idea where many of the service worker labour will go now though
