Unfortunately I agree with this - I'm currently doing some work in tech across sub-saharan Africa and what we're seeing is that local devs from Cameroon to Kenya to Tunisia (okay not sub-saharan but we happen to have an office there) who are any good are now working on the global marketplace and not available to local companies with rare exceptions (e.g. junior who haven't figured out how to compete globally yet or happen to both have the preference to work in person and don't want to move away).
