who wrote about the emerging white collar class in the 1950s
New class A theory of the new class was developed by Milovan Đilas the Vice President of the Federal People's Republic of Yugoslavia under Josip Broz Tito, who participated with Tito in the Yugoslav People's Liberation War, but was later purged by him as Đilas began to advocate democratic and egalitarian ideals (which he believed were more in line with the way socialism and communism should look like). However, there were also personal antagonisms between the two men, and Tito felt Đilas undermined his leadership. The theory of the new class can be considered to oppose the theories of certain ruling Communists, such as Joseph Stalin, who argued that their revolutions and/or social reforms would result in the extinction of any ruling class as such.[1][2] It was Đilas' observation as a member of a Communist government that Party members stepped into the role of ruling class – a problem which he believed should be corrected through revolution. Đilas' completed his primary work on his new class theory in the mid-1950s. While Đilas was in prison, it was published in 1957 in the West under the title The New Class: An Analysis of the Communist System.
