I don't agree much on this. For ex, hiring someone from Nigeria is always cheaper than hiring the same person in US for a US based company.
It's my impression that companies would rather hire 2-3 locals/non-remote workers and enhance their productivity with AI tools, vs. hiring 15 people from abroad that are in countries they have no presence in.
AI is undercutting a lot of these remote abroad jobs, because those types of tasks are more easily done with AI now.
Or when inadequately capitalized.
