Adding more competition isn't an answer, because competition is about individual profit, thus monopoly. Neo-liberalism, global free market etc do encourage a world-wide competition: it's already the current trend. What you probably mean is some kind of "healthy/fair competition": the fact we need to add another adjective hints that this is about doing something to balance it. I argue this is about encouraging cooperation. A good balance between both leads to interdependence, which is exactly what we would like: a state where everyone has some possibility of moving around a bit, but where nobody is free to ignore what people they interact with have to say. A ref i really want to push: "Mutual Aid: A Factor of Evolution" (1902, Kropotkine). There is a whole part mostly about the evolutionary analysis of altruism (the rest is about analyzing several human social orders throughout history: pre-medieval villages, medieval cities and 19c industrial cities).
