AI is again the topic of the day and people are discussing what to do about the coming “job-pocolypse.” It seems AI can do anything we humans can do better and so 30% or more of jobs will be destroyed and replaced by AI. Leaving aside how accurate that prediction is, if 30% of all jobs will be impacted then it does warrant a public policy response. Everyone’s got their own personal favorite, but one I see come up again and again is that companies should face a hefty tax any time they replace a worker with AI.

To be blunt, taxing companies for replacing workers with AI is a terrible idea. Let’s leave aside the argument of “how do you prove it,” and cut straight to the fact that the government should not be taxing technological progress. Just to start with some history, how many farmers were displaced by tractors? Millions. In 1900 40% of Westerners worked on farms, now it’s less than 5%. Tractors meant that a single farmer could do the labor of tens or hundreds of men, and so they could fire many of their farm hands to be replaced by tractors. But does anyone reading this wish nearly 1/2 of us were still farmers? Should the government have heavily taxes tractors to preserve the idyllic rural farm life?

The argument in favor of taxing companies that replace workers with a machine is that the company is becoming more profitable at the expense of the worker, and they should pay it back. The current hullabaloo is about being replaced by AI, but in the 20th century similar calls were made when factory workers were being replaced by robots. The problem with this argument is that ignores society. The worker and the company are not the only 2 pieces of the equation, society in general benefits when companies become more efficient. Technology is deflationary, and it has allows many products to drop or price or not increase as rapidly as wages in general. Food today costs less as a percent of annual income than at nearly any time in history, and a large part of that is because the cost of food is decoupled from the cost of labor. So farm hands being replaced by tractors helped all of society by giving us cheaper food, and all of society would have been harmed if taxes had been instituted to prevent tractors from becoming commonplace.

Are the workers harmed when their jobs are replaced by AI? Yes of course. But society itself is helped and so all of society should bear the costs of helping the workers. We should of course offer unemployment benefits and job retraining to those affected. We should not let them go by the wayside the way we did to blue collar factory workers in the 20th century.

But neither should we shoot society in the foot by blocking technological progress that will help all of us. AI replacing jobs will mean products will become cheaper relative to wages, just as what happened with food. A lot of people also spread nonsense that unemployment will skyrocket as the displaced workers can’t find other jobs. They misunderstand economics, there will always be demand for more jobs. The price of some goods will decrease thanks to AI, but that means that people can buy more of those goods or buy more of others goods that they put off buying because they were forced to choose and only had so much money. As prices fall, demand will rise, raising demand for labors in other areas, and a new equilibrium will be reached. Those jobs lost due to AI don’t mean the workers will be forever jobless, any more than 35% of the population displaced by tractors meant that unemployment skyrocketed in the 20th century. Time and time and time again technology has replaced the jobs of workers, and the workers have found new jobs. It will happen again with AI.
