They also boot-strap economies. Individuals with good product ideas, a field of consumers, and cheap labor can produce large numbers of goods that can be exported as well as consumed in local economies. This is much harder to do when dealing with labor that has an upward force applied to its wages, either by being artificially limited (as in current immigration policies) or by requiring a rare skill. Economies aren't zero-sum games. I really don't get why more people don't understand this.
