The author assumes that national innovation equals national success, thus explaining the pre-eminence achieved by innovative Europeans. His main approach focuses on the effects of technological advances on the relative prosperity of Europe's nation states over the last 1500 years.
From Germany to the United Kingdom many of those nation states are younger than those of the New World, so there's a flaw for a start. Indeed, what was a nation until recently? It's hard to define particularly when empires were involved, and that's relevant here because the author does much of his analysis with reference to the British economy. So what does he mean by Britain? Like most non Brits he probably means England and maybe the bits around it. But little England stayed little, which would explain his ludicrously low numbers for the size and growth rate of the "British" economy when imperial Britain was becoming enormous. It's like treating the economy of ancient Rome in terms of that of the city of Rome- a nonsense. Similarly, he constantly calls America, Australia, Canada and New Zealand European (as in continental European) offshoots. Tell that to the Queen of England who is still the Head of State for 3 of them. (He saves a worse insult for the Greeks and Italians by calling the Byzantine Empire non-European, which is a downright racialist slur.)
The contemporaneous economic impacts of empires and incessant wars are barely mentioned let alone studied, which is an astonishing omission that gives the book a suspiciously European Union propaganda tone. The emphasis on innovation being everything leads the author to conclude that Portugal, Spain and Britain declined through lack of it. No, they collapsed under the weight of the empires he ignores. For example, while its empire and therefore its economy was going through the floor Britain gave the World; antibiotics, stereophonic recording, polyethylene production, radar, television, synthetic lubricants, computers, jet engines, microwave generators, holograms, float glass, jet airliners, nuclear power stations, liquid crystal displays, microchips, mini cars, cash machines, body scanners, the world wide web...(about all of which the author seems ignorant). Only when it stopped innovating did the by then post imperial Britain prosper again, so disproving his theory.
The author is wrong, it wasn't pan-European innovation and meddling by politicians and economists that made Europeans globally pre-eminent, it was the empire building activities of the Portuguese, the Spanish, the Dutch and most of all the British. The rest were either bit-part players or irrelevant, it was Pax Britannica not Pax the European Union. That pre-eminence was destroyed by the Germans and their many collaborators in 2 World Wars, leaving Europe a backwater. Those are truths about the History of Europe, economic or otherwise, that some, particularly the federalists still cannot stomach hence revisionist works like this.
