On The Power Broker

The Power Broker is a book about how power actually works, studied at the level of a single unelected man who reshaped a city and was never once chosen by the voters to do it. Robert Caro spent seven years on the life of Robert Moses, who held appointed positions in New York for more than four decades and used them to build the roads, bridges, parks, and housing that physically remade the metropolis, accumulating along the way a power greater than that of the mayors and governors who nominally outranked him. The result, published in 1974, is one of the greatest works of American nonfiction and a permanent education in the nature of power.

Caro's central subject is not Moses the man but power itself, where it comes from, how it is gathered, and what it does to the person who holds it. The revelation of the book is that the most consequential power in a democracy is often not the visible, elected kind but the hidden, administrative kind, lodged in the authorities and commissions and appointed bodies that the public never votes on and barely notices. Moses understood this before anyone, and built his empire on it, drafting the legislation that created his own positions, structuring public authorities so that their revenues and their decisions answered to him rather than to elected officials, making himself indispensable and then untouchable.

The book is a study in how such power is assembled and how it corrupts. Caro traces Moses from an idealistic young reformer into a figure of immense arrogance and cruelty, displacing hundreds of thousands of people for his highways, contemptuous of the poor and of public transit, answerable to no one. The early idealism and the later ruthlessness are connected, Caro argues, by power itself, by what decades of unchecked authority do to a person.

The Power Broker belongs in a library of the republic because it teaches a lesson the formal study of government often misses: that the structures of power matter more than the personalities, that the way authority is arranged determines who can be held accountable and who cannot, and that a democracy can be quietly reshaped by people the public never elected and could not remove. Moses built much of value and much that did lasting harm, and he did both without ever facing the voters. Understanding how that was possible is essential to understanding how power really operates in a modern democratic state.

It is also, simply, one of the most absorbing books ever written, a biography that reads like an epic and a civics lesson disguised as a tragedy. It pairs naturally with Caro's life of Lyndon Johnson, also on these shelves, his even larger study of the same subject, power, pursued through a very different career.

The Power Broker is in copyright and widely available in print and digital editions. It is long, more than a thousand pages, and worth every one. Read it to understand power as it is actually held and used, beneath the visible surface of elections.
