Markets are true democracies. The allocation of resources, capital and labour is achieved through the mechanism of spending, and so based on spending preferences. As money flows through the economy the popular grows and the unpopular shrinks. Producers receive a signal to produce more or less based on spending preferences. Markets distribute power according to demand and productivity; the more you earn, the more power you accumulate to allocate resources, capital and labour. As the power to allocate resources (i.e. money) is widely desired, markets encourage the development of skills, talents and ideas.
Planned economies have a track record of failure, in my view because they do not have this democratic dimension. The state may claim to be “scientific”, but as Hayek conclusively illustrated, the lack of any real feedback mechanism has always led planned economies into hideous misallocations of resources, the most egregious example being the collectivisation of agriculture in both Maoist China and Soviet Russia that led to mass starvation and millions of deaths. The market’s resource allocation system is a complex, multi-dimensional process that blends together the skills, knowledge, and ideas of society, and for which there is no substitute. Socialism might claim to represent the wider interests of society, but in adopting a system based on economic planning, the wider interests and desires of society and the democratic market process are ignored.
