By the late 1950s, three distinction conceptions of the welfare state had formed in West Germany, each with strong connections to a particular world view. Father Oswald von Nell-Breuning, in the tradition of Catholic social thinking, defended social policies as a dialectical combination of solidarity and subsidiarity, which could counter the inequities of capitalism to help integrate workers into society and ensure human dignity. Hans Achinger, with his roots in private charity and social work, by contrast, was skeptical of the institutions of the welfare state and described how programs created a permanent bureaucracy with a popular clientele, manipulated information, and had a series of unintended consequences on state, family, and individual alike. Ludwig Preller, finally, the leading Social Democratic expert on social policy, justified extensive social policies as a way to empower individuals, to give them the tools they needed to shape their own lives.
