Toronto's main business lobby, the Board of Trade, recently called for the outsourcing of public transit services to private companies, part of their free advice to the next mayor on reducing the city's deficit.

On one level, it's an unremarkable proposal: just the latest in a chorus of business demands that governments fix their deficits by selling, contracting out or eliminating public services. But it caught my eye because I am residing temporarily in Auckland, New Zealand's biggest city, where the transit system is the most fragmented, expensive and maddening I've ever used. And it's 100-per-cent private. The gory details provide a caution for those who believe the private market always does things better.
