Mr. Tea
Let's Talk About Ceps
The free market is necessarily more efficient because that's its nature. Nationalised British industries like the railways are in a mess because of ridiculous bureaucracy - the exact opposite of good liberal economics.
Efficient *at what*? Providing a service to consumers? Or making money for shareholders?
The free-market argument that privatised industry is more efficient because there's competition completely breaks down when you're talking about public services or public transport, when there is (very often) a complete monopoly exerted by one company in any given field over the people who live in a given area. If I decide Thames Water is giving me poor value for money I can't just decide to switch supplier to Yorkshire Water instead, can I?
