Workers vs Machines

A recent item in the NY Times dealt with the fact that many companies these days seem relatively reluctant to invest in new employees, but comparatively willing to invest in new machinery. The evidence for that is mostly anecdotal, but interesting none the less.

Here’s the story, by Catherine Rampell: Companies Spend on Equipment, Not Workers

Companies that are looking for a good deal aren’t seeing one in new workers.

Workers are getting more expensive while equipment is getting cheaper, and the combination is encouraging companies to spend on machines rather than people….

The story gives the distinct impression that the issue here is not just an issue of machines or people; it’s about machines versus people, and machines are clearly winning the hearts and minds of employers these days. On the face of it, that sounds bad. Workers — people — matter, from a moral point of view, and machines don’t. So, other things being equal, it is better to spend money on doing something good for people (e.g., providing someone with a job) than it is to spend money on mere machines.

But two perhaps-not-obvious points need to be made, here.

The first point is that even when employers choose to purchase machines instead of hiring employees, that needn’t be a bad thing socially, nor bad for labour as a group. Machinery tends to boost productivity, and boosting productivity boosts wealth, so from a social point of view (including from the point of view of blue-collar workers) it is good when companies invest in machinery. Even if machines displace workers in a given industry, that needn’t spell trouble for workers as a class. In the early 19th Century, Luddites destroyed mechanized looms in a vain attempt to forestall the effect of the industrial revolution on employment patterns in the textile industry. And yet, in the long run, the industrial revolution did nothing to worsen the lot of labourers. Indeed, it ushered in an era of prosperity that made the lot of labourers as a whole vastly better. To be sure, changes in technology result in unemployment in the particular sectors in which new technologies are introduced. But that tends to be a temporary problem. The standard Econ 101 example is transportation. The advent of the automobile surely resulted in some unemployment among those who had formerly worked in the horse-and-buggy industry. But, in the long run, those workers eventually found jobs in the auto industry, and were no worse off. And so on.

The second point is that, even if we focus on the employees of a particular organization, labour and machines are not always (and maybe not even often) in competition. Machines and tools can make employees’ lives better, and in those cases, certainly, spending money on machines and tools is a good thing. The most obvious case is when the equipment purchased is, say, safety equipment, or when the machines purchased are ones with additional safety features or features that make work less back-breaking.

But purchase of equipment can also be good in another way. Machines and tools of various kinds can make labour more productive, and more productive labour is more valuable. Not everyone realizes that the productivity of labour — the amount of goods that can be turned out per hour of a worker’s time — varies vastly across the globe. An hour of an American worker’s labour, for example, produces far more output than an hour of a Chinese worker’s labour. And the reason has little to nothing to do differences in work ethic or intelligence or talent. The difference lies in national differences in access to tools, and to differences in organizational and managerial strategies. So investing in better equipment can be a way of investing in the productivity of your workers.

Of course, past some threshold, when labour is more productive, employers may decide they need less of it. The most famous example of this is in farming, where one man with a big tractor now often does the work that a dozen men might have done in years gone by. But the devil is in the details. We should at least recognize that investment in machinery is not automatically contrary to the interests of labour.

    An Alternative to Capitalism (which we need here in the USA)

    Several decades ago, Margaret Thatcher claimed: “There is no alternative”. She was referring to capitalism. Today, this negative attitude still persists.

    I would like to offer an alternative to capitalism for the American people to consider. Please click on the following link. It will take you to an essay titled: “Home of the Brave?” which was published by the Athenaeum Library of Philosophy:

    Excellent post Chris and great points. Also interesting to make these considerations in the context of Corporate IT and general technological investments.
