Ronald Reagan once described an economist as someone who, when they see something working in practice, wonders if it will work in theory, and in 2014 Martin Ricketts and I provided the theory. We showed that, contrary to myth, science is not publicly-available (how many readers of this document can read Einstein’s papers, even though those papers are over a century old?) Rather, science is open only to fellow scientists – who pay for their access by the papers they themselves contribute. And when science is mode led as a “contribution good,” the need for government funding disappears.9
One more, longitudinal, piece of American evidence shows governments need not fund science. Whereas before 1940 almost all American pure science was funded privately, today the private sector (in the shape of industry, foundations and universities) funds only half of it: the other half is funded by federal agencies including the NSF and the National Institutes of Health. And whereas before 1940 almost all US R&D was funded privately, by 1989 the federal government was funding two thirds of it (today it is only a third). Yet since 1830 the long-term rates of GDP per capita and TFP (total factor productivity) growth in the US have been steady (with GDP per capita, for example, growing at just under 2% per annum) and the inauguration of the federal funding for science had the following effect on long-term rates of GDP per capita and TFP growth: none.
Conclusion
The evidence that governments need not fund science for economic reasons is overwhelming, and it is ignored only because of self-interest: the scientists like public funding because it frees them to follow their own interests, companies like it because it provides them with corporate welfare, and politicians like it because it promotes them as patrons of the public good (witness Bill Clinton’s leading the celebrations over the mapping of the human genome.) So the empirical evidence is ignored in favo r of abstract theories.
There are, of course, non-economic reasons, such as defense or the study of pollution, why a government might want to fund science (and a democratic polity, moreover, might not wish to be dependent only on private entities for its expertise in science) but in this document I cannot pronounce on these non-economic justifications for the government funding of research: only democratically-elected representatives have that competence. Here I can make only the technical argument that there is no credible evidence that governments need fund science for economic reasons.
But we can nonetheless note that in his own farewell address (known for its regrets for the “industrial-military” complex and for the “three and half million men and women directly engaged in the defense establishment”) Truman’s immediate successor as President lamented the effects of the federal government’s funding for science. He lamented the effects on the universities:
In the free university, historically the fountainhead of free ideas and scientific discovery … a government contact becomes virtually a substitute for intellectual curiosity.
The prospect of domination of the nation’s scholars by federal employment … is gravely to be regarded.
And he also lamented the effects on the federal government itself:
We should be alert to the … danger that public policy could itself become captive of a scientific-technological elite.

Notes
1 It is commonly asserted that Germany overtook the UK during the 19th century, but Angus Maddison is one of many economic historians to have shown that is not true (The World Economy 2007, OECD). 19th century Germany excelled in certain areas of technology such as chemicals, but in other areas such as agriculture it so lagged that, overall, its economic performance was mediocre. It can be compared to the Soviet Union: by 1957, with the launch of Sputnik, the USSR was clearly the world’s leading space power; it was also dirt poor.
2 The federal and state governments were spending $81 million pa compared to the private sector’s $265 million, which included $31 million for university and foundation research (T Kealey, 1996, The Economic Laws of Scientific Research, Macmillan, p 151). Almost all the governments’ research was for agriculture (which was economically irrelevant) or defense (defense research has only about 10 per cent of the economic value of civil research; Advisory Council On Science and Technology, 1990 Developments in Biotechnology HMSO, London).
