It is also flawed for you to conclude that dropping the gold standard was the reason behind the unemployment. There were many things happening that could also have contributed to it.

Here is a more complete graph of unemployment during the Great Depression where you will notice the unemployment levels never reaching the peak, and dropping back down with Roosevelt enacting even more policies and spending bills.
