The republic's welcoming corporate tax policy has been a success, but it depends heavily on just a few big names

In 1958, a young Irish civil servant named Kenneth Whitaker surprised his political masters in Dublin with a 250-page document on which he and some of his colleagues in the department of finance had been covertly working for months. Its title, Economic Development, may have been deceptively bland, but its message was blindingly clear. The country was an economic mess and unless radical action was taken its very existence as a viable state was in doubt.

As the writer Fintan O'Toole put it in his memoir, 1950s Ireland was basically a vast cattle ranch with a few cities and a lot of small provincial towns attached". This ranch had two main exports: live cattle and beef products, most of them destined for the British market, and young people, emigrating in their thousands every year because there were no livelihoods, or any prospect of fulfilling lives, at home.
