John Steinbeck's 'The Grapes of Wrath' also speaks urgently to today's concerns: the cratered trail of dreams for Mexican immigrants seeking a promised land in the Western [United States]; the perfidy of banks in foreclosing on poor people's homes; and the insurgent urge of the book's protagonist, Tom Joad, to speak truth to police power. 'Wherever there's a cop beatin' up a guy,' Tom promises, 'I'll be there.' In Salinas, Calif., Ferguson, Mo., or Staten Island, N.Y., Tom's truth goes marching on.
