 The neoliberal case against socialism is based on three concerns: inefficiency, conflict, and power. Socialism is inefficient, generates social conflict, and concentrates power in dangerous ways. Let’s begin with inefficiency, the familiar argument that socialist economies impoverish society vis-à-vis  capitalism.[5]  Hayek’s early claim to fame was his role in what is called the socialist calculation debate, which concerned how socialist planners can plan the production and distribution of capital goods without the use of a price system. Socialists argued that planners should be able to plan by collecting preference and production information from citizens. Ludwig von Mises (1922 [1936/1951]) began the debate by arguing that, without a price system, the information required to plan the economy did not exist. Without a price system, there is no information for planners to collect and compute. Oskar Lange (1936) replied that socialist managers of firms could mimic market prices. Hayek (1945) disagreed with Lange; even if the information required to plan the economy existed, it would be too hard to collect and impossible to compute before the relevant information changed. The problem is that the information required to plan the economy is not given to anyone. For Hayek, we can plan the economy
