Now is not the time to defend sweatshops

Abstract arguments about the benefits of outsourcing have no place in defending criminal negligence, here or overseas.

Yesterday Rana Plaza, a Bangladeshi clothing factory and shopping mall, collapsed, killing hundreds and injuring thousands. According to BBC News, "the factory owners had ignored warnings not to allow their workers into the building after cracks were noticed on Tuesday." As a result, the Bangladeshi High Court has summoned the owner of the building, as well as senior staff at the factories, to appear before the court next week. The factory owners themselves are reported to have gone into hiding.

The Telegraph's David Blair is unequivocal: we take the blame.

One of Rana Plaza’s factories – New Wave – supplied Primark, the bargain clothing chain with 161 branches in Britain, and Bonmarché, another budget retailer with its head office in Wakefield and 360 stores across the country. They may not have known it, but these two companies were buying products made by people working in a death trap.

But the rush to the counterintuitive take is quicker every day. In fact, write Alex Massie and Matt Yglesias, we shouldn't be so quick to jump to conclusions. Yglesias writes:

Bangladesh may or may not need tougher workplace safety rules, but it's entirely appropriate for Bangladesh to have different—and, indeed, lower—workplace safety standards than the United States.

The reason is that while having a safe job is good, money is also good… Bangladesh is a lot poorer than the United States, and there are very good reasons for Bangladeshi people to make different choices in this regard than Americans. That's true whether you're talking about an individual calculus or a collective calculus.

While Massie adds:

It would be better if more buildings in Bangladesh met existing, local, safety regulations. It may well be that western companies could and should do more to monitor the conditions in which their contractors work. Be that as it may, sweatshops in the developing world have, on balance, been a good thing. And it is not even close.

The question of the morality of sweatshops is an old one. So old, in fact, that many consider it settled, giving arguments like Paul Krugman's 1997 piece "In Praise of Cheap Labour" the final word.

And indeed, those arguments – and the bulk of Massie's piece is also comprised of defending sweatshops in general – are convincing. Workers in sweatshops frequently earn more than the agricultural labourers that they are recruited from, and usually enjoy better conditions to boot, so in a way, they aren't treated badly at all. And the labourers are paid from money overseas, rendering sweatshops a sort of decentralised international aid: you buy clothes from Primark, and Primark gives some money to a poor Bangladeshi labourer! It's almost like charity.

But not only is the value of sweatshops to developing nations not actually a settled argument, it bears very little relationship to the issue at hand here.

Rana Plaza's building standards were illegal under Bangladesh's own laws. This is not a case of hardy foreign workers taking jobs that westerners wouldn't; nor is it a case of the cost of living being lower overseas, enabling cheaper goods with less money spent on wages. It is a case of criminal exploitation of labour: criminal by our standards, and criminal by Bangladesh's

The argument in defence of sweatshops relies on the point that free and equal exchange is mutually beneficial. That's claimed on a national level, that Britain exchanging money for Bangladeshi labour makes Britain and Bangladesh better off, and on a personal one, that employers exchanging money for employee's labour makes them both better off. But the deal here was not free and equal: employees were not warned that the danger of their job had increased vastly after the first cracks were noticed four days ago. There was no choice, there was no mutually beneficial exchange. There was just exploitation, and death.

There is a time for the defence of sweatshops. That time is not now. Now is the time for asking why it is that our international companies can't even buy from suppliers which follow the meagre labour protections which are afforded to workers in the developing nations they operate in.

Primark, for its part, says that "the company is shocked and deeply saddened by this appalling incident at Savar, near Dhaka, and expresses its condolences to all of those involved." But sadness is not the point. When Primark, and Bonmarché, and all the other contractors who squeeze margins down to the last penny, start using suppliers who actually live up to the minimum standards already in place, then we can have the argument about whether those standards ought to be raised. That's the time Krugman's argument might be needed. But today, the wrongdoing is clear, and the last thing needed is a defence of it.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
