Många känner till att ekonomipristagaren Milton Friedman lanserade idén om skolpeng 1955. Han är emellertid inte den enda ekonomipristagare som är positiv till ett sådant system: i The Constitution of Liberty, som i år fyller 50 år, skriver F. A. Hayek (s. 329):
As has been shown by Professor Milton Friedman, it would now be entirely practicable to defray the costs of general education out of the public purse without maintaining government schools, by giving the parents vouchers covering the cost of education of each child which they would hand over to schools of their choice. It may still be desirable that government directly provide schools in a few isolated communities where the number of children is too small (and the average cost of education therefore too high) for privately run schools. But with respect to the great majority of the population, it would undoubtedly be possible to leave the organization and management of education entirely to private efforts, with the government providing merely the basic finance and ensuring a minimum standard for all schools where the vouchers could be spent.
Hayeks tveksamhet inför offentliga skolor har främst att göra med det skäl som John Stuart Mill tar upp i On Liberty:
A general State education is a mere contrivance for moulding people to be exactly like one another: and as the mould in which it casts them is that which pleases the predominant power in the government, whether this be a monarch, a priesthood, an aristocracy, or the majority of the existing generation, in proportion as it is efficient and successful, it establishes a despotism over the mind, leading by natural tendency to one over the body.
