Government’s task is to achieve the common good. If it takes a long time markets will not do it: banks do not lend beyond the payback time horizon. For better and worse, government acts as the risk taker of last resort. Laissez-faire arose out of the Victorian fossil fuel windfall. But rich societies see beyond the private horizons of business. After WW1 they set to safeguard security by means of infrastructure, healthcare, education, housing, and social insurance. Government authority, alone or in partnership with business, is prone to corruption. The antidote is an independent, expert, and honest civil service. In 1980 politics moved in the opposite direction, imposing business norms and seeking to impose a corporate model on government activity. An opportunistic public–private partnership is no match for pressing social challenges, nor is the academic delusion of self-sufficient free markets. In the face of private impatience, government acts as a commitment agent for society.
