Arthur Seldon on the problem of “who guards us from the guardians”? (1990)
The founder of the Institute of Economic Affairs, Arthur Seldon (1916-2005), argues that advocates of limited government have still yet to solve this most important political problem:
The difficulty with limited government that liberals have yet to resolve is that its functions must be exercised through the imperfect political process that distorts and manipulates individual preferences. Who makes the rules that politicians are to enforce in the public interest if not the politicians themselves? Quis custodiet ipsos custodes? Limited government implicitly supposes that government will perform faithfully the main functions allotted to it even though it is judged incompetent in performing other functions. The notion of limited government lacks the indispensable instinctive scepticism of government taught by the classical liberal economists that led them to want government confined to its unavoidable minimal functions of public goods rather than to the indeterminate limited functions that could be decided by government itself. If government cannot be expected to perform acceptably the services it can leave to the market, it cannot be expected to devise neutrally the rules that decide the services it must perform itself.
