Answer:
The Cash Crop System implies that the different plantations of vegetables, crops and other agricultural products are commercialized and monetized, thus abandoning these plantations their subsistence characteristics to join the world market of marketable raw materials.
Thus, the American landowners began to see that their agricultural products no longer only allowed them to subsist through the consumption or barter of their products, but that they could now also sell them to obtain a greater economic profit.
This led to the promotion of a large-scale exploitation of the different plantations, which encouraged landowners to begin importing slaves from Africa to be used as labor in order to maximize production. In addition, this same system made many European migrants see America with good eyes, given the enormous availability of land to exploit that the nation possessed.
