My impression from talking with a few people from India working in UK and working with Indian outsourcing agencies/contractors is that India routinely gets cost cutting projects based on price/employee - this creates "coder farms" which breed code farm quality developers + the education system on the whole is inferior (from what I understand India took diploma mills to the next level). So the best talent emigrates because even with the remote option, the increase in life standard and opportunities from emigrating are worth it, and low skill/almost bot level development for rent culture reinforces itself.
