It is being reported today that the UK Chancellor of the Exchequer will announce a large increase in public expenditure and mention has been made of increasing spending on roads.
It should be clear from the precepts of this site that all future spending should be made on those activities, which on the balance of probabilities will reduce resource intensity. At this point it is not clear that spending on road construction, or aviation facilities will reduce the resource intensity of mobility.
A second and more general point is that all spending must aim to employ and increase the knowledge and skills of the indigenous population. Spending that draws in and relies on external knowledge and skills will only reduce the possiblity of paying back current borrowing.
