The government is right that we need to invest more. There is room for disagreement about what we need to invest in, and how much of it should be paid for by taxpayers.
The government’s current plans include the expensive and wasteful £20 bn for carbon capture and storage. They need to give greater priority to
New gas turbine electricity generators to keep the lights on and power new data centres
A fleet of smaller cheaper nuclear reactors
Several new reservoirs to ensure plentiful future supplies
New drainage pipes with more capacity
More domestic oil and gas to displace imports which produce more CO 2
More broadband and data processing capacity
More bypasses and dual carriageway strategic local roads
More motorway capacity
Digital signalling throughout the railway network to expand train capacity
Many of these projects can and should be privately financed.
The main problem with the Rachel Reeves idea that we can afford to borrow more in the public sector is it assumes the investments made by the state will produce income and profit and will be able to pay the interest and then repay the debt. Recent experience says this is unlikely. HS2, a new nationalised railway is more than three times over budget, long delayed and little prospect of any revenue let alone profit anytime soon. The nationalised Post Office was given large sums to invest in new computers, only to send its innocent staff to prison and land taxpayers with a large compensation bill. The high spending nationalised railways as a whole lose large sums before subsidy and burden taxpayers with large debts.
Changing the way the debt control is calculated to allow more investment only works if all the investments make money after paying for the debt. If they turn out to be like the railways or the Post Office borrowing more means more debt, more burdens and higher taxes.
