Marx and Lenin were ahead of their time. Marx wrote before offshoring of jobs and the
financialization of the economy. Lenin presided over a communist revolution that jumped the gun by taking place in a country in which feudal elements still predominated over capitalism. In 21st century America capitalism has been unfettered from the regulations that democratized it and made it serve society. Today capitalism is being financialized with the consequence that its productive power is being drained into the service of debt.

Few earned their billions by producing goods and services sold to consumers.
