Imperialism, the Highest Stage of Capitalism
In "Imperialism, the Highest Stage of Capitalism" (1916), Vladimir Lenin further developed Marxist theory and argued that capitalism necessarily led to monopoly capitalism and the export of capital—which he also called "imperialism"—to find new markets and resources, representing the last and highest stage of capitalism. Some 20th century Marxian economists consider capitalism to be a social formation where capitalist class processes dominate, but are not exclusive.
