Problems of market economies

From Encyclopedia Britannica:

"By the end of the 19th century, some unforeseen but serious consequences of the Industrial Revolution in Europe and North America had produced a deepening disenchantment with the principal economic basis of classical liberalism—the ideal of a market economy. The main problem was that the profit system had concentrated vast wealth in the hands of a relatively small number of industrialists and financiers, with several adverse consequences. First, great masses of people failed to benefit from the wealth flowing from factories and lived in poverty in vast slums. Second, because the greatly expanded system of production created many goods and services that people often could not afford to buy, markets became glutted and the system periodically came to a near halt in periods of stagnation that came to be called depressions. Finally, those who owned or managed the means of production had acquired enormous economic power that they used to influence and control government, to manipulate an inchoate electorate, to limit competition, and to obstruct substantive social reform. In short, some of the same forces that had once released the productive energies of Western society now restrained them; some of the very energies that had demolished the power of despots now nourished a new despotism."

"As modern liberals struggled to meet the challenge of stagnating living standards in mature industrial economies, others saw an opportunity for a revival of classical liberalism. The intellectual foundations of this revival were primarily the work of the Austrian-born British economist Friedrich von Hayek and the American economist Milton Friedman. One of Hayek’s greatest achievements was to demonstrate, on purely logical grounds, that a centrally planned economy is impossible. He also famously argued, in The Road to Serfdom (1944), that interventionist measures aimed at the redistribution of wealth lead inevitably to totalitarianism. Friedman, as one of the founders of the modern monetarist school of economics, held that the business cycle is determined mainly by the supply of money and by interest rates, rather than by government fiscal policy—contrary to the long-prevailing view of Keynes and his followers. These arguments were enthusiastically embraced by the major conservative political parties in Britain and the United States, which had never abandoned the classical liberal conviction that the market, for all its faults, guides economic policy better than governments do."
