There is nothing wrong with private capital financing infrastructure. In the UK it has worked very well for broadband cables. The Thames tideway tunnel to give London more dirty water handling capacity has been a model project financed by the private sector.
There is much wrong with bogus private finance schemes of the kind Labour went in for when it was last in government. PFI for NHS hospitals or state schools often turned out to be dear money, locking the state into expensive service contracts and dear borrowing.
The Chancellor thinks she can take pressure off her borrowing by going for PFI. There is a great danger that she allows deals that leave substantial risk with taxpayers. Markets will regard this as more back door state borrowing. Taxpayers will pay more to borrow this way. Public spending will continue out of control.The public sector must not lock itself into more bad contracts through its inability to specify a fair terms contract and stick to it.
State investment has brought us the disasters of HS 2 and Post Office computerisation. Labour’s last PFI s lumbered too many schools, hospitals and the taxpayer with too many long term bad contracts just to get the debt off the state’s books at great cost. The debt is still out there, and the taxpayer has to pay.
