So that person, even if they are highly skilled, will instead have to work at a low skill job for low wages . Not because they have lower skills, but because their government is looking out for the wealthy asset class as opposed to the working class and those other countries(like India) do not legally allow US citizens to live and work in their lower cost of living country.
I know of many companies with outsourced talent, that have a local office in the US where clerical workers and the janitors of the building make higher wages than the overseas outsourced engineers. And those clerical workers and janitors do not make enough income in the US to have decent housing or health care. They are forced, by the laws of the lower cost of living countries, to stay in the US and live poorly.
I’m shocked how naive people seem to be in these threads about remote work. There is tons of remote work. There already has been for decades. It’s called outsourcing. The reason you can’t find remote jobs in high wage countries is because no one would be crazy enough to pay those wages for remote workers when they can find the same level of talent for less than half the price.
