There were two "new deals" during the Great Depression era-one that was aimed at restoring the economy from the top down and the other aimed at restoring the economy from the bottom up. The first new deal started with The Agricultural Adjustment Act that was passed in 1933. This act basically reduced food production and made smaller farmers go out of business. The government started with this plan because the main problem was not the amount of food they had but the distribution of goods.
The main thing that helped America out of the depression was World War II, but that's another story for a different time.
