Prices, supply and demand, production relations in markets, all derive from complex interactions between individuals who each contribute to the optimisation of a small part of the larger social process. If a single committee were to replace it with planning the entire dance of the market, then this small group of people would have to ponder the endless series of choices and plans. This kind of intricate calculation is beyond the capabilities of even the most skilled engineers. Decades before Mises wrote, computer science and information theory had not yet emerged, and he had no way of formalizing these intuitive formulations. Many of Mises's claims were rejected by mainstream economists, whose increasingly narrow mathematical approach to the field was also despised by Mises.
Mises' critics, including Lange and Fred. Taylor (Fred Taylor) and Abba. Abba Lerner, arguing that the market mechanism is only one of many ways of planning the economy, and is far from the most efficient one. They looked at the economy from a purely mathematical point of view, not an operational point of view, and believed that the (very huge) system of equations whatsapp list relating to the supply and demand of various goods, resources, and services was, in principle, not difficult to solve. In the simplified economic blueprint, the average person plays the role of both producer (labor, capital provider, etc.) and consumer.
As consumers, people have different preferences for various goods and services. Some people like chocolate, some like vanilla. As producers, they have different talents and abilities. Some people are good at math, some people are very good at reassuring customers. In principle, the only thing we need to do is figure out people's preferences and abilities, assign jobs to those who are most competent, and distribute the value created by producing the goods and services that people really want.
