Free markets depend on truth telling. Prices must reflect the valuations of consumers; interest rates must be reliable guides to entrepreneurs allocating capital across time; and a firm's accounts must reflect the true value of the business. Rather than truth telling, we are becoming an economy of liars. The cause is straightforward: crony capitalism.

Thomas Carlyle, the 19th century Victorian essayist, unflatteringly described classical liberalism as "anarchy plus a constable." As a romanticist, Carlyle hated the system—but described it accurately.

Classical liberals, whose modern counterparts are libertarians and small-government conservatives, believed that the state's duties should be limited (1) to provide for the national defense; (2) to protect persons and property against force and fraud; and (3) to provide public goods that markets cannot. That conception of government and its duties was articulated by the Declaration of Independence and embodied in the U.S. Constitution.

Why has this happened? Financial services regulators failed to enforce laws and regulations against fraud. Bernie Madoff is the paradigmatic case and the Securities and Exchange Commission the paradigmatic failed regulator. Fraud is famously difficult to uncover, but as we now know, not Madoff's. The SEC chose to ignore the evidence brought to its attention. Banking regulators allowed a kind of mortgage dubbed "liar loans" to flourish. And so on.
