The primary benefit to the economy of Britain's New England colonies from the Atlantic slave trade was that New England’s shipbuilders earned profits by providing ships for the triangular trade.
New England played a significant role in the triangular trade, which involved the exchange of goods and people between Europe, Africa, and the Americas. Shipbuilders in New England constructed vessels that were used to transport enslaved Africans to the Americas, as well as to carry raw materials back to Europe. This trade brought wealth and economic growth to New England, even though the region itself was less reliant on slave labor compared to the southern colonies.
