Cost-benefit analysis is systematically rigged in favour of business. Take, for example, the decision-making process for transport infrastructure. The last government developed an appraisal method which almost guaranteed that new roads, railways and runways would be built, regardless of the damage they might do or the paltry benefits they might deliver(8). The method costs people’s time according to how much they earn, and uses this cost to create a value for the development. So, for example, it says the market price of an hour spent travelling in a taxi is £45, but the price of an hour spent travelling by bicycle is just £17, because cyclists tend to be poorer than taxi passengers(9).
