My high school American Literature class mentioned the unrest of the Great Depression more than my history classes did.
American history class quickly rushed past (or skipped outright) everything after the Civil War to get to WWI, the Great Depression pretty much just as a leadup to WWII, WWII for like two months, then a little bit of the Civil Rights movement.
In college we spent a lot more time on those gaps, which is what all the "liberal brainwashing" is about.
