I got thinking today about garbage trucks. More specifically, I got thinking about the workers on those garbage trucks. Even more specifically, I got thinking about how it seems there are less workers on garbage trucks these days than there used to be.

For most of my life, a garbage truck had two workers on it. Someone who drove and someone who would jump off and empty the bins into the truck. My town, like many others, has adopted the trucks with the big mechanical claw on the side of it that lifts the garbage can from the curb and dumps its contents into the truck. It now only takes one worker to both drive and operate the claw.

It reminds me of grocery stores. When I was a kid, every cash register had two workers: a cashier and someone to bag the groceries. I remember when they got rid of the bagger job, all of a sudden you were expected to bag your own (or the cashier might do it for you). Today, in many grocery stores, a single worker can oversee a dozen different self-checkouts.

My grandfather worked his whole life in a GM plant. The threat of automation to jobs is nothing new. I think what is important to keep in mind is that it's not often an abrupt replacement. It's usually many small, different changes—often presented as opportunity for efficiency or skill learning—each one making human work slightly more redundant. Death by a thousand paper cuts.

In 1958, Hannah Arendt pondered what happens to a society of labourers that becomes "liberated" from the bonds of labour when labour is all this society knows. Of that, she wrote, "surely nothing could be worse."
