“A tax can never be favorable to the public welfare, except by the good use that is made of its proceeds.”

"The Social Responsibility of Business is to Increase its Profits" in The New York Times Magazine (13 September 1970) http://www.colorado.edu/studentgroups/libertarians/issues/friedman-soc-resp-business.html
Context: On the level of political principle, the imposition of taxes and the expenditure of tax proceeds are governmental functions. We have established elaborate constitutional, parliamentary and judicial provisions to control these functions, to assure that taxes are imposed so far as possible in accordance with the preferences and desires of the public — after all, "taxation without representation" was one of the battle cries of the American Revolution. We have a system of checks and balances to separate the legislative function of imposing taxes and enacting expenditures from the executive function of collecting taxes and administering expenditure programs and from the judicial function of mediating disputes and interpreting the law.
Here the businessman — self-selected or appointed directly or indirectly by stockholders — is to be simultaneously legislator, executive and, jurist. He is to decide whom to tax by how much and for what purpose, and he is to spend the proceeds — all this guided only by general exhortations from on high to restrain inflation, improve the environment, fight poverty and so on and on.

1900s, A Square Deal (1903)
Context: The welfare of each of us is dependent fundamentally upon the welfare of all of us, and therefore in public life that man is the best representative of each of us who seeks to do good to each by doing good to all; in other words, whose endeavor it is not to represent any special class and promote merely that class's selfish interests, but to represent all true and honest men of all sections and all classes and to work for their interests by working for our common country. We can keep our government on a sane and healthy basis, we can make and keep our social system what it should be, only on condition of judging each man, not as a member of a class, but on his worth as a man. It is an infamous thing in our American life, and fundamentally treacherous to our institutions, to apply to any man any test save that of his personal worth, or to draw between two sets of men any distinction save the distinction of conduct, the distinction that marks off those who do well and wisely from those who do ill and foolishly.
