Governmental involvement in the economy
In a 1962 essay that builds on arguments made by A. V. Dicey, Friedman argued that a "free society" would constitute a desirable but unstable equilibrium, due to an asymmetry between the visible benefits and the hidden harms of government intervention; he uses tariffs as an example of a policy that brings noticeable financial benefits to a visible group, but causes worse harms to a diffuse group of workers and consumers.
Friedman was supportive of the state provision of some public goods that private businesses are not considered as being able to provide. However, he argued that many of the services performed by government could be performed better by the private sector. Above all, if some public goods are provided by the state, he believed that they should not be a legal monopoly where private competition is prohibited; for example, he wrote:
There is no way to justify our present public monopoly of the post office. It may be argued that the carrying of mail is a technical monopoly and that a government monopoly is the least of evils. Along these lines, one could perhaps justify a government post office, but not the present law, which makes it illegal for anybody else to carry the mail. If the delivery of mail is a technical monopoly, no one else will be able to succeed in competition with the government. If it is not, there is no reason why the government should be engaged in it. The only way to find out is to leave other people free to enter. In 1962, Friedman criticized Social Security in his book Capitalism and Freedom, arguing that it had created welfare dependency. However, in the penultimate chapter of the same book, Friedman argued that while capitalism had greatly reduced the extent of poverty in absolute terms, "poverty is in part a relative matter, [and] even in [wealthy Western] countries, there are clearly many people living under conditions that the rest of us label as poverty." Friedman also noted that while private charity could be one recourse for alleviating poverty and cited late 19th century Britain and the United States as exemplary periods of extensive private charity and eleemosynary activity, he made the following point:
It can be argued that private charity is insufficient because the benefits from it accrue to people other than those who make the gifts – ... a neighborhood effect. I am distressed by the sight of poverty; I am benefited by its alleviation; but I am benefited equally whether I or someone else pays for its alleviation; the benefits of other people's charity therefore partly accrue to me. To put it differently, we might all of us be willing to contribute to the relief of poverty, provided everyone else did. We might not be willing to contribute the same amount without such assurance. In small communities, public pressure can suffice to realize the proviso even with private charity. In the large impersonal communities that are increasingly coming to dominate our society, it is much more difficult for it to do so.
Suppose one accepts, as I do, this line of reasoning as justifying governmental action to alleviate poverty; to set, as it were, a floor under the standard of life of every person in the community. [While there are questions of how much should be spent and how, the] arrangement that recommends itself on purely mechanical grounds is a negative income tax. ... The advantages of this arrangement are clear. It is directed specifically at the problem of poverty. It gives help in the form most useful to the individual, namely, cash. It is general and could be substituted for the host of special measures now in effect. It makes explicit the cost borne by society. It operates outside the market. Like any other measures to alleviate poverty, it reduces the incentives of those helped to help themselves, but it does not eliminate that incentive entirely, as a system of supplementing incomes up to some fixed minimum would. An extra dollar earned always means more money available for expenditure.
Friedman argued further that other advantages of the negative income tax were that it could fit directly into the tax system, would be less costly, and would reduce the administrative burden of implementing a social safety net. Friedman reiterated these arguments 18 years later in Free to Choose, with the additional proviso that such a reform would only be satisfactory if it replaced the current system of welfare programs rather than augment it. According to economist Robert H. Frank, writing in The New York Times, Friedman's views in this regard were grounded in a belief that while "market forces ... accomplish wonderful things", they "cannot ensure a distribution of income that enables all citizens to meet basic economic needs". Friedman also criticized urban renewal programs in the United States due to their racially discriminatory and economically regressive effects.
In 1979, Friedman expressed support for environmental taxes in general in an interview on The Phil Donahue Show, saying "the best way to [deal with pollution] is to impose a tax on the cost of the pollutants emitted by a car and make an incentive for car manufacturers and for consumers to keep down the amount of pollution." In Free to Choose, Friedman reiterated his support for environmental taxes as compared with increased environmental regulation, stating "The preservation of the environment and the avoidance of undue pollution are real problems and they are problems concerning which the government has an important role to play. ... Most economists agree that a far better way to control pollution than the present method of specific regulation and supervision is to introduce market discipline by imposing effluent charges."
In his 1955 article "The Role of Government in Education", Friedman proposed supplementing publicly operated schools with privately run but publicly funded schools through a system of school vouchers. Reforms similar to those proposed in the article were implemented in, for example, Chile in 1981 and Sweden in 1992. In 1996, Friedman, together with his wife, founded the Friedman Foundation for Educational Choice to advocate school choice and vouchers. In 2016, the Friedman Foundation changed its name to EdChoice to honor the Friedmans' desire to have the educational choice movement live on without their names attached to it after their deaths.
Michael Walker of the Fraser Institute and Friedman hosted a series of conferences from 1986 to 1994. The goal was to create a clear definition of economic freedom and a method for measuring it. Eventually this resulted in the first report on worldwide economic freedom, Economic Freedom in the World. This annual report has since provided data for numerous peer-reviewed studies and has influenced policy in several nations.
With sixteen other distinguished economists he opposed the Copyright Term Extension Act, and signed on to an amicus brief filed in Eldred v. Ashcroft. Friedman jokingly described it as a "no-brainer".
Friedman argued for stronger basic legal (constitutional) protection of economic rights and freedoms to further promote industrial-commercial growth and prosperity and buttress democracy and freedom and the rule of law generally in society.
Friedman suggested medical savings accounts, repealing tax exemptions of employer-provided medical care and income-based deductibles as ways to lower health care costs in America. Friedman also argued that federal involvement in health care should be restricted, with state and local governments financing health care for the poor.
Friedman believed the government should not operate national parks. He argued that Yellowstone National Park should be sold for private development.
