Between 1607 and 1692, the rise in use of slaves as a form of labor shows that there was no socio economic mobility in the American colonies. Slavery developed gradually over this period but become extremely prevelant after Bacon's Rebellion (1676). This system of slavery ensured that enslaved Africans had no legal rights, were considered property, and could not earn wages. No matter how hard these individuals worked, they were still considered property and earned no money for their production. This is a perfect example of the lack of socio economic mobility in the colonies during the 17th century.
