Final answer:
South Carolina became wealthy under mercantilism through its supply of valuable raw materials, utilization of enslaved labor, and benefit from monopolistic trade with England, which provided a secure market.
Step-by-step explanation:
South Carolina was able to become rich under the economic system of mercantilism because it had the perfect conditions that the system favored. The colony possessed valuable raw materials, such as rice, indigo, and furs, which were in high demand in Europe. Additionally, the use of enslaved labor provided a cheap and efficient workforce that enabled the mass production of these commodities. Furthermore, the monopoly trade conditions enforced by the mercantilist system ensured that South Carolina's goods were exported to England, which provided a secure market for those goods while also allowing England to benefit by manufacturing and selling finished products back to the colonies.
Under mercantilism, South Carolina's economy thrived as it became integral to the triangular trade, providing raw materials to England, and participating in the trade of enslaved individuals from Africa. The established legal framework of slavery based on the Barbados slave codes solidified this exploitative economic structure. Ultimately, by adhering to the principles of mercantilism, South Carolina developed a wealthy class of planters and contributed to the economic growth of the British Empire.
