How did the economy and labor system in Virginia and other southern colonies change? In the Virginia colony, tobacco as a cash crop changed the economic  system by requiring more slaves to meet demand. The economy changed  into a plantation economy where onlâ¦y a few cash crops were grown.  Cotton, sugar cane, tobacco, and rice were the cash crops that  provided the wealth for the southern colonies.
Black slavery took root in the American colonies slowly. Historians now know that small numbers of Africans lived in Virginia before 1619, the year a Dutch ship sold some twenty blacks (probably from the West Indies) to the colonists. But it was not until the 1680s that black slavery became the dominant labor system on plantations there.
