The evidence is they end up paying more. I think the example of the U.K. may be one of the most tangible for us to see. After 30 years of rail privatization and public-private partnership projects all over its rail system, it's now one of the most expensive rails in Europe, not just to operate but for the passengers. It also has worse working conditions for workers when compared to other systems, like the French or the German ones, which have remained in public hands.
On top of that, they had to extend contracts. When you look at the Eurotunnel, which was a public-private partnership project, they had to extend that concession by 40 years because the profits of the private concessioners were not guaranteed in the original span of time they had said, which was 55 years. That's another example where the public ends up paying and also we pay more than originally stipulated.
