by Max Shachtman. Shachtman had developed a Marxist critique of Soviet communism as "bureaucratic collectivism," a new form of class society that was more oppressive than any form of capitalism. Shachtman's theory was similar to that of many dissidents and refugees from Communism, such as the theory of the "new class" proposed by Yugoslavian dissident Milovan Djilas. Shachtman's ISL had attracted youth like Irving Howe, Michael Harrington, Tom Kahn and Rachelle Horowitz. The Young People's Socialist League was dissolved, but the party formed a new youth group under the same name. The Second Red Scare is a period lasting roughly from 1950 to 1956 and characterized by heightened fears of Communist influence on American institutions and espionage by Soviet agents. During the McCarthy era, thousands of Americans were accused of being communists or Communist sympathizers and became the subject of aggressive investigations and questioning before government or private-industry panels, committees and agencies. The primary targets of such suspicions were government employees, those in the entertainment industry, educators and union activists. Suspicions were often given credence despite inconclusive or questionable evidence and the level of threat posed by a person's real or supposed leftist associations or beliefs was often greatly exaggerated. Many people suffered loss of employment and/or destruction of their careers; and some even suffered imprisonment. Most of these punishments came about through trial verdicts later overturned, laws that would be declared unconstitutional, dismissals for reasons later declared illegal or actionable, or extra-legal procedures that would come into general disrepute. The most famous examples of McCarthyism include the speeches, investigations and hearings of Senator McCarthy himself; the Hollywood blacklist, associated with hearings conducted by the House Un-American Activities Committee (HUAC); and the various anti-communist activities of the Federal Bureau of Investigation (FBI) under Director J. Edgar Hoover. It is difficult to estimate the number of victims of McCarthyism. The number imprisoned is in the hundreds and some ten or twelve thousand lost their jobs. In many cases, simply being subpoenaed by HUAC or one of the other committees was sufficient cause to be fired. Many of those who were imprisoned, lost their jobs or were questioned by committees did in fact have a past or present connection of some kind with the CPUSA. However, for the vast majority both the potential for them to do harm to the nation and the nature of their communist affiliation were tenuous. The African
