To what extent is outsourcing positively impacted the global economy?

For the answer to the question above, I believe the answer is  Outsourcing to other country finds the most efficient way to get a task completed. In addition, the cost of salary and cost of living in other countries like India is lower so they could pay less to the workers and they can cut some cost. Also spreads the wealth around a bit instead of just keeping it inside the country.
I hope this helps. Have a nice day!
