Since the 20th century, with the development of private monopoly capitalism, how has Britain and the United States handled it?

The reason why the United States has become a trust empire and a typical country with the most developed monopoly capital is inseparable from the characteristics of monopoly capitalist economic development in its social countries. There is no deep-rooted feudal system in American history, with a vast domestic market and abundant natural resources; The United States is a new capitalist country, getting rid of the old fixed capital and making full use of foreign advanced technological achievements, a large amount of funds and a large number of immigrant labor. These conditions enabled the United States to successfully make full use of the achievements of the technological revolution in the 1970s during the period of 65438-09, and set up many large enterprises on the basis of the latest technology from the very beginning, which is the so-called American industrial Britain, and this is colonial imperialism. Britain is the first country to embark on the capitalist road and realize the industrial revolution. It is the most powerful capitalist country and "world factory" in the stage of free competition capitalism. However, after entering the stage of monopoly capitalism, its economic development slowed down relatively, the speed and degree of industrial production concentration, the number of monopoly organizations and the degree of economic dominance were lower than those of the United States and Germany, and the establishment of monopoly organizations was later than that of the United States and Germany 10 ~ 15 years. The great development of British monopoly organizations was in the 1990s of 19. By the beginning of the 20th century, although most departments had different forms of monopoly organizations, some old industrial sectors, such as textiles, coal and iron smelting, were still in a state of decentralized operation, which was related to Britain's slow economic development and heavy burden on the old industrial sectors, as well as its laissez-faire and loose trade policies.
