As relevant today as it was when first published in 1914, Other People's Money, and How the Bankers Use It is an important collection of essays written by author and anti-trust lawyer Louis Brandeis.

Explaining how banks have become a powerful oligarchy, Brandeis describes how the money trusts hold enormous and growing influence upon almost every large industry in the United States and much of the wider world. The monopolies of money trusts, and their role in controlling the economy, are described in detail. Brandeis attacks the use of investment funds to promote the consolidation of various industries under the control of a small number of corporations.

This revolutionary work contributed to the growing push for financial regulation, and its ideas influenced the creation of laws such as the Federal Reserve Act and the Clayton Antitrust Act, which were intended to curb the power of monopolies and promote fair competition.
