For one, there wasn't exactly a labor shortage. Because of the economic theory of mercantilism, the colonies were established to produce a surplus of goods. In other words, the only reason there was a labor shortage was because the colonies had been established in the first place for the purpose of creating tons and tons of mostly unnecessary stuff (like tobacco).
