The Economist is apparently under the sway of the dreaded ‘labor metaphysic’:
Nevertheless, the unions are far from a spent force: the 7m Britons who still carry union cards remain, collectively, an important social movement (by comparison, only around 4m people attend church once a month or more). Concentration in the public sector has helped to preserve their power. Strikes by transport workers can cause chaos if commuters are unable to get to work. A recent two-day walkout by workers on the London Underground, for example, caused widespread disruption in the capital; one estimate, from the London Chamber of Commerce, put the cost to firms at £48m ($75m) a day. A full-blown rail strike would be much worse. A walkout by teachers would require millions of parents to stay at home minding their children; binmen could leave the streets as filthy as some were in the “winter of discontent”; and so on.
