“Would you like fries with that?” may soon be a long forgotten relic of American pop culture.

McDonald’s employees who picketed for a better living wage (whatever that means) may come to regret that decision. According to a Redditor, a McDonald’s in Illinois replaced their cashiers with machines. The machines appear to be the cousins of the ones found in grocery stores, big box stores, and CVS that allow customers to complete transactions.

How cost effective is replacing an organic employee with a mechanized one? According to an economic blog, and unsurprisingly, the machines likely come out on top in terms of pricing:

For a location open 24 hours: The cost of human cashiers, not counting benefits, $15/hour * 24 hours * 365 days/year = $131,400

For a location open 6AM to Midnight: $15/hour * 18 hours * 365 = $98,550.

For the machine to be cost effective, all it needs to do is cost less than $100,000 a year to buy and maintain.

Who could’ve possibly seen this coming? Forbes. They predicted this exact scenario last July.

A recent article at the Huffington Post makes the claim that if McDonald’s MCD +0.26% doubled its employees salaries it would only cause the price of a Big Mac to go up by 68 cents. The implication here is that 68 cents isn’t much money, so they should do it. There’s a few things missing from this. One is that the article itself alleges that doubling wages would lead to a 17% increase in costs. And I guess this is obviously supposed to seem like a small amount? It doesn’t look that way to me. What do people expect will happen when prices go up 17%? If McDonald’s could raise its prices by that much without lowering demand they would. No, what would happen is people would shop at those stores less, there would be less profit and less McDonald’s stores to hire workers. Doubling of labor costs will simply increase a fast food restaurant’s incentives to adopt technology like this. And if fast food wages doubled everywhere it would spur the development of these technologies even faster.

This is all basic economics, really. As costs of labor increase the added cost must be offset. In order to satisfy operating costs, produce a product consumers want to purchase, and still turn a profit, it’s perfectly reasonable for a company like McDonald’s to look for cost-cutting alternatives. As Forbes pointed out, the added pressure to increase wages only serves to expedite technological solutions.

But cooks are safe from the machination of American fast food, right?

Not if companies like Momentum Machines has anything to do with it. “Our technology will democratize access to high quality food making it available to the masses,” their site claims. They also claim their burger making machines can, “do everything employees do except better” and that the machines reap such large labor savings, restaurants will be able to afford twice as fancy ingredients. Tempting little proposition they have there.

“Would you like fries with that?” may soon be a long forgotten relic of American pop culture. And all because it makes good economic sense.

Update (WAJ): Prof. Reynolds notes that Robot makers must be loving the recent NLRB ruling, as well, which held McDonald’s parent corporation liable for franchisee employment practices. Can a kiosk file an employment grievance?
