Copyright allows that. It increases the amount of property in the world. And it generally does not need a great deal of resources to produce. While I don't think that the third world could produce enough art, books or music to enter the world economy, I do think they could produce software or other practical intellectual goods that the world wants and which would allow them in. There is no freedom without economic freedom.
Economic freedom requires property.
Without property people are enslaved by nature or by others. Allowing them to produce property empowers them and gives them dignity. Property is not the problem. Especially now when property can be produced by the intellectual powers of the person. This is an extension of self and is important as that.
