Britain privatized its Royal Mail in 2013, proceeding with an initial public offering of shares that raised about $2.7 billion. The government pursued the reform because the company faced falling mail volume, and it needed to reduce costs and increase innovation. Similar issues face the U.S. Postal Service.

The Financial Times has named the reformer leading the privatized Royal Mail its “Person of the Year.” Below is an excerpt about Moya Greene from FT’s story. I have two questions: i) Why don’t we get reforms or reformers like this in Washington? ii) Why are American leaders so comparatively timid in embracing market-based reforms?

Ask anyone who knows Moya Greene, the Canadian chief executive who last year steered Royal Mail, the UK’s 500-year-old postal service, into the private sector, and the same phrases come up. “She’s relentless, a force of nature, a tough lady,” says one admirer.

It took a determined personality to get this behemoth, with £9bn of revenues and 150,000 staff, into a healthy enough state to be floated on the London Stock Exchange, where it went straight into the FTSE 100 index. The goal of privatising Royal Mail had defeated governments for 40 years.

Greene, 59, has been Royal Mail’s chief executive for almost four years, the first woman and first non-Briton to run it since Henry VIII established a “master of the posts” in 1512. Her previous role heading Canada’s postal service – and as a civil servant overseeing the privatisation of that country’s railway and deregulation of its airline and ports systems – gave her the necessary blend of industrial and political experience.

With this British privatization—and past ones—people have quibbled with some of the details. But, all in all, privatization in Britain has been hugely successful. Prime Minister Cameron should be applauded for having the guts to build on the privatization reform legacy of Thatcher, Major, and Blair.

Meanwhile on this side of the pond, Republican Darrell Issa is having trouble getting his own nominally conservative party to accept even small changes to the broken government postal system. Perhaps he could kick-start reforms by inviting Moya Greene to give testimony to his high-profile committee.
