The uninspiring ideas and promises from both main parties since the election was announced make for a depressing read. In trying to get our votes – promising not to put up taxes and to look after pensioners – they are seeking to deliver the cakeism we, the consumers and voters, want: more and better services, without paying for them. It is our votes they are bidding for, and the election campaigns reflect what they think we will vote for.

In the face of the massive capital maintenance and investment needs across many sectors (infrastructure, the NHS, education, water, energy), someone has to pay. Not only do we not want to pay higher bills, we want to borrow to finance the investment, rather than saving to pay for it. Net of capital depreciation, saving in the UK is negative.

It would take a brave political leader to spell out what would really be needed to re-industralise the UK (to manufacture all the wind turbines, nuclear reactors and solar panels), to transform our health and education services, to provide a proper defence system, and to restore our natural environment.

All of this costs, but we don’t want to pay. We want a free lunch. This is not sustainable for our citizens, societies and businesses. The opinion polls suggest that people don’t buy this empty promise, yet they seem set to vote for it. Because it is not sustainable, it will not be sustained. All the promises we like hearing will turn out to be empty – we will have to pay for our lunch.
