It is, however, an imperfect parallel. That is partly because Japan is relatively unified whereas Europe is quite the reverse, but equally because young Japanese in general accept the benefits of the Japanese system, whereas a sizable proportion of young Europeans don’t accept the limitations of Europe. They emigrate, perhaps to jobs in the UK or US, or they don their gilets jaunes. The slowest-growing European economies, Italy and Greece, have seen proportionately the largest outflows of the highly qualified young.
