His speech is titled “Economic Lessons from American History,” (printable PDF version) and one of the lessons has to do with loser-pays:

…if Jefferson’s decimal coinage concept was a good idea that quickly spread around the world, another idea that developed here at that time was lousy: the so-called American Rule, whereby each side in a civil legal case pays its own court costs regardless of outcome. This was different from the English system where the loser has to pay the court costs of both sides.

The American Rule came about as what might be called a deadbeat’s relief act. The Treaty of Paris (which ended the American Revolution) stipulated that British creditors could sue in American courts in order to collect debts owed them by people who were now American citizens. To make it less likely that they would do so, state legislatures passed the American Rule. With the British merchant stuck paying his own court costs, he had little incentive to go to court unless the debt was considerable.

The American Rule was a relatively minor anomaly in our legal system until the mid-20th century. But since then, as lawyers’ ethics changed and they became much more active in seeking cases, the American Rule has proved an engine of litigation. For every malpractice case filed in 1960, for instance, 300 are filed today. In practice, the American Rule has become an open invitation, frequently accepted, to legal extortion: “Pay us $25,000 to go away or spend $250,000 to defend yourself successfully in court. Your choice.” …

…policing the marketplace has long been considered a quintessential function of government. The reason for this is that when policing has been in private hands, self-interest and the public interest inevitably conflicted. The private armies of the Middle Ages all too often turned into bands of brigands or rebels. The naval privateers who flourished in the 16th to 18th centuries were also private citizens pursuing private gain while performing a public service by raiding an enemy’s commerce during wartime. In the War of 1812, for instance, American privateers pushed British insurance rates up to 30 percent of the value of ship and cargo. But when a war ended, privateers had a bad habit of turning into pirates or, after the War of 1812, into slavers.

Predictably, the American Rule has spread exactly nowhere since its inception at the same time as the decimal coinage system. There is not another country in the common-law world that uses it. … Few things would help the American economy more than ending the American Rule.
