Guest worker programs enable better mobility compared to strict immigration rules, but the U.S. already demonstrates a degree of free movement among its states. The lack of significant migration from rural areas to urban centers, despite perceived differences in desirability, illustrates the influence of market forces. High costs of living in desirable cities like New York City deter migration due to expensive rents, while lower costs in places like Kansas keep residents from moving. Wages in desirable areas are often lower relative to living costs, further impacting the decision to relocate. These economic dynamics show how mobility within a system can function without leading to chaos.
