The postwar diversification and pluralization of psychoanalysis in the United States

In the years after World War II, Ego Psychology came to dominate much of the Anglo–American psychoanalytic world, although the Kleinian and Middle Groups continued to work quite creatively. Postwar economic growth and the expansion of the welfare state supported the expansion of both research and mental health services to wider populations, calling for more varied and flexible psychodynamic techniques, especially in the United States. In addition, new currents began to surface in Continental Europe and Latin America, which were to eventually garner more attention.
