All I know is that the only thing that brought the world out of the Great Depression is World War II. Sucks to think of it that way, but it's the truth. The world needed people to manufacture weapons, factories were built, and those factories needed to be worked. Lots of jobs right there.
As for Nina's explanations, I'm wishing that I took government and economics a year early like everyone else I know instead of waiting a year so I can take AP... DX I feel so lost.
