This is strictly my opinion but I believe it was a failure. It's original goal was the revitalize the American economy and pull us out of the Great Depression and get American's working again. In this it succeeded to an extent lowering the unemployment rate significantly however it still did not completely work since 15% of the United State's population was still jobless and in poverty. It won't be until WWII and the building of the arms industry as well as army that we will pull ourselves from the Great Depression.
Feudalism was the dominant social system in Medieval Europe. Under Feudalism, the king owned all of the land and distributed it amongst lords who gave an oath of fidelity, or loyalty.
