Which statements below best describe the state of the southern economic infrastructure during the civil war?

The South was crippled. Once Abe Lincoln took slavery in certain parts of the south. There economy dropped because the people there thrived on selling slaves based on their height and brute agility. Also they needed slaves to plant crops and do much percentage of labor. No slaves, no profit or gain. This was Abraham's own strategic plan to not completely break the south, but cripple the economy to weaken them during the war.
