1. Slave labor was needed for the colonies because there wasn't enough people living inside the south too help farm. Also it was cheaper to get slaves from africa (which is forced to work for their owner for life most of the time) instead of hiring a bunch of Southern farm hands to help them.
2. Cash crops were grown to make BIG money, however, you can't really eat it ( i mean you can try eating tobacco (idk if it can be eaten) or cotton (definetely not). Substinence crop is for eating. Even though you don't make much money selling them, you are able too feed your family (and sell the extras for profits)
3. An artisan slave gets a lot more freedom and are usually treated better than a normal slave because they are skillful in needed stuff. An example of an artisan slave can be found in the book "Stealing South" in which Mr. Ezekiel, the artisan slave 'knows a lot of things' and that there isn't a lot of things that he doesn't know about that goes around that area. He also states that because of his knowledge, he was given greater freedom than most slaves.
hope this helps :D
D. it would protect individual citizen freedom
