What Happened to the Textile Towns

Between 1965 and 1990 the British textile industry lost roughly four fifths of its jobs. Three causes are usually given, and they are not equally weighted. Cost is the one most often cited. Spinning and weaving are labour-intensive, and wages in the countries that took the work were a fraction of British wages. This explains a great deal. Investment matters too. Much British machinery dated from before the war. Where firms did re-equip — and some did — they survived longer, which suggests the cost argument is not the whole story. The third cause is the hardest to see: the industry was concentrated. A car plant closing takes a town's largest employer; a mill closing often took its only one, along with the suppliers and the shops that depended on it. That concentration is why the closures show up in the population figures of particular towns and not in national ones.

Can You Do Two Things at Once?

People say they multitask. Mostly they do not. The brain can run two tasks together only if at least one is automatic. Walking and talking works because walking is automatic for an adult. Reading and listening to speech does not, because both need the same language system. What feels like multitasking is usually rapid switching. Each switch costs time — a fraction of a second to disengage and re-engage — and the costs add up. In experiments, people doing two tasks alternately take substantially longer in total than doing them one after the other, and make more errors. They also do not notice. Switching feels efficient because you are busy the whole time. The practical conclusion is unpopular but consistent: for anything demanding, doing one thing at a time is faster.
