We remember Venice as a city of merchants, though it would be truer to call it a city of makers. At its height the Venetian Arsenal was the largest industrial complex in Europe – sixteen thousand workers assembling galleys from standardised, interchangeable parts moved along a canal, a production line in everything but name, three centuries before Henry Ford. When Henry III of France visited in 1574, his hosts reportedly assembled a complete galley in the time it took him to finish a banquet. Add Murano glass, silk weaving and the largest printing industry of the Renaissance, and the picture sharpens. Venetian wealth was made in Venetian workshops long before it was traded across Venetian wharves.

Then, slowly and almost invisibly, the city stopped making things. The usual explanation blames Vasco da Gama, whose route around the Cape of Good Hope let Portugal bypass the Mediterranean spice trade. That mattered, yet it remains the less interesting half of the story. The deeper rot was internal. Patricians who had once sent their sons to sea and into the workshops began converting commercial fortunes into landed estates on the mainland. Guilds hardened into cartels defending old methods instead of improving them. Wages stayed high while productivity stagnated, and Dutch and English yards learnt to build cheaper, better ships. The Arsenal, once the wonder of Europe, drifted into ceremonial irrelevance. The capital remained – Venice stayed rich, ornate and magnificent for another two centuries – but it had become a rentier city, living off accumulated assets rather than current production.

A country living off what it once built has quietly stopped being wealthy and started spending slowly.

The end, when it came, was almost embarrassingly quiet. In May 1797 the Great Council of a republic that had lasted eleven hundred years voted itself out of existence rather than resist Napoleon's army. There was no siege and no last stand, because beneath the marble there was nothing left to fight with – no industrial base, no navy worth the name, no productive class with a stake in the outcome. The lion of St Mark had become a museum exhibit while still nominally alive.

The photograph of an empty beach

Now move to the other end of the story. South Korea emerged from war in 1953 as one of the poorest countries on Earth, with a per-capita income below much of sub-Saharan Africa, no meaningful natural resources and its industry flattened. Its most generous foreign advisers recommended rice and textiles. The World Bank explicitly counselled against a Korean steel industry, judging that the country had no business making things at all.

Korea ignored the advice, and the manner of it has become industrial legend. When Chung Ju-yung of Hyundai sought British financing for a shipyard in 1971, he had no yard, no orders and no track record. He reportedly produced a 500-won banknote bearing the geobukseon – the ironclad turtle ship Korea had built in the sixteenth century – together with a photograph of an empty beach at Ulsan, and argued that a nation which had made armoured warships three hundred years before the West could presumably manage a few tankers. He got the loan, sold ships that did not yet exist, and built the yard and the first vessels at the same time. That empty beach is today the largest shipyard in the world.

The same pattern repeated across the economy. POSCO poured its first steel in 1973 and grew into one of the most efficient producers anywhere. Samsung moved from sugar and textiles into semiconductors that now sit in most of the world's devices. Within two generations – a single working lifetime – South Korea travelled from post-war destitution to the front rank of industrial economies, and the sequence is worth noting. Steel came first, then ships, cars and chips, and only afterwards the banks, the brands and the cultural exports the world now takes for granted.

What manufacturing actually is

Set the two stories side by side and the lesson reaches well beyond a fondness for factories. Manufacturing behaves less like an output than like a capability, and capabilities compound. A country that makes things accumulates process knowledge, supplier networks, engineering talent and the unglamorous discipline of tolerances, deadlines and quality systems. That accumulated competence then spills over into everything else – logistics, software, design, finance. Services can grow tall, but they grow tall on an industrial root system. Venice let the root system die and kept admiring the foliage; Korea planted the roots first and let everything else follow.

There is a harder edge to the lesson, too. Production capability doubles as resilience. Venice in 1797 could not defend itself because, in the most literal sense, it no longer knew how to build what defending itself required. The countries now reshoring semiconductor plants, rebuilding shipyards and treating industrial policy as security policy have simply reopened the Venetian file.

I think about this often, because I spend much of my working life on and around factory floors – in foundries, machine shops and quality departments, with the engineers and managers who make things for a living. Poland is one of Europe's genuinely industrial nations, and that base deserves to be treated as the strategic asset it is. The people running those plants negotiate with international clients, defend their processes in audits and present to foreign boards, all in English. Helping them do it with precision is my small contribution to keeping the Arsenal working. History is unsentimental about the alternative.
