Today's Glenn Beck "Crash Course" episode looks at revisionist history, and offers actual history to correct it.

About the unconstitutional authoritarian abuses of Woodrow Wilson, and how a rejection of Wilson's policies prevented a great depression in the early 1920's and established a period of massive growth for a decade afterward.
How FDR's economic policy resulted in deepening the Great Depression and prolonged it, till war manufacturing finally ended the depression in 1940-41.
The ugly marxist, racist and corrupt side of unions.
And the real Margaret Sanger, who fully embraced eugenics and genocide.
