This book goes through --one might even say races through-- the life of this very influential economist. Born in 1912 in Brooklyn, New York City (at that time almost entirely Jewish) Friedman was the son of Jews who had emigrated from Carpatho-Ruthenia, i.e. the bit of Hungary which abuts Poland and the Ukraine. The young Friedman's easy progress through school and university (Chicago University and also Rutgers (New Jersey) is palpable. At that time, in the 1930's, an intellectual Jew would probably go for either Marxism-Leninism or for Zionism, so Friedman was not quite mainstream in always being a fervent pro-capitalist (though he made the point that Marx himself always believed in controlling the money supply firmly). The fact that he was at (and taught at) Chicago is relevant, I feel, that vibrant all-American city, far from the disturbing ideologies of New York City. The book does not fully or really at all explore these aspects, but keeps to a straight and narrow biographical path.
The book does not say whether Friedman had any strong political views not directly emerging from his economic views. He appears to have been "an early and consistent interventionist" as far as US entry into WW2 is concerned. In other words, like so many American Jews, he was willing to fight Hitler to the last drop of someone else's blood. Apart from that, this book says little of him, politically, though his advisor status to Barry Goldwater in 1963-1964 is noted. By that time, he had achieved eminence. Just before then, he visited Europe, the Soviet Union and Israel and India. Unlike many Jews, he did not make his trip a kind of "Holocaust" pilgrimage but simply kept his eyes open. Unimpressed, unsurprisingly, by provincial Russia/Ukraine, he went on to Yugoslavia, Israel and then India, where the author says that he was perceptive in predicting some economic events. Perhaps so, but then, G.K. Galbraith, one of his most trenchant opponents (though Friedman seems to have held him in little academic regard) often did the same though basing his judgment calls on opposed ideas; Galbraith also bet on the stock market very successfully (as did a much earlier economis, Ricardo), so one cannot say "he was right" just because he predicted some events correctly.
I felt at the end that Friedman was a bit like those intelligent robots in films like Westworld, run out of control when put in a sector outside his intellectual comfort zone. Alternatively, like a flat graph which suddenly goes manic. He seems to have believed that the poor, disabled, elderly, sick, unemployed should just be left unaided at all by the State and that their welfare should be left to "the market" and private charity by individuals. To me, that view leads to Thatcherism and Reaganomics, when (as happened) politicians of limited abilities (and yes that does include Mrs Thatcher...) think that they have been intellectually influenced by books like Capitalism and Freedom. That might lead, as in Weimar Germany, to a popular and nationalist uprising...
I am not an economist and would have liked some analysis about whether (as I assume) or not money or the money supply is to be regarded simply as another commodity, a commodity like any other except for its purchasing flexibility.
Not bad but a bit flat in the end. On the other hand, the book is good for the general reader (like me).
