I think it is distasteful and disrespectful to the tens of millions of workers in the public sector to portray them as inefficient and lazy and the salvation can only come from the private sector. I fail to see how a sector where market efficiency is not possible (think BAA's competition at Heathrow) can save money only because it is run by private companies. Cannot compare easily garbage collection with motorway building and management.
Infrastructure projects yield a return that can be captured by public or private sector if the project is run well. I see no conceptual issue with the government raising money to get a return from running roads. The government aim seems to be take out of the books any expenditure to allow for tax cuts, even if this is based on highly uncertain projections, i.e. the taxes are cut in the hope things will turn out well as the "problem" is passed into private hands.
Private companies are not exempt from being poorly managed. Governments can incur losses and users of goods or services supplied by private companies can be unhappy. I recall the 4 inches of snow that blocked Heathrow because a private company would not invest in equipment as it makes more P&L sense to keep travellers stranded for a few days than to keep machines parked in mild winters.
Bailing out the efficient private sector is not a great idea as we all recently learned. And that was the pride of London, one of the most incentivized, dynamic, innovative, deregulated, globalized and competitive sectors one could think of... Shame it failed. What if a privately built bridge, with a £8 toll each way collapses just as the Northern Rock? Cynically - the Hammersmith flyover doesn't really look like the ultimate engineering challenge, so I am not too trustful in post Victorian concrete structures.
Now talking about leases, I suggest the home ownership in Britain be measured by number of freehold households, surely the number is less flattering than the current 60-65%. Leasehold is not full ownership in the same way road leases are not privatisations.
Why not outsource the PM job by the way?
