A basic economic premise holds that when the price of something rises, people seek to economize on its use. They seek substitutes for that which has risen in price. Recent years have seen proposals for an increase in the federal minimum wage to $15 an hour. Some states and localities, such as Seattle, have already legislated a minimum wage of $15 an hour.
Nobody should be surprised that fast-food companies such as Wendy's, Panera Bread, McDonald's and others are seeking substitutes for employees who are becoming costlier. One substitute that has emerged for cashiers is automated kiosks where, instead of having a person take your order, you select your meal and pay for it using a machine. Robots are also seen as an alternative to a $15-an-hour minimum wage. In fact, employee costs are much higher than an hourly wage suggests. For every employee paid $15 an hour, a company spends an additional $10 an hour on non-wage benefits, such as medical insurance, Social Security, workers' compensation and other taxes.
The vision that higher mandated wages (that exceed productivity) produce no employment effects is what economists call a zero-elasticity view of the world -- one in which there is no response to price changes.
It assumes that customers are insensitive to higher product prices and investors are insensitive to a company's profits.
There is little evidence that people are insensitive to price changes.
The issue is not whether people change their behavior when relative prices rise or fall; it is always how soon and how great the change will be.
McDonald's might try to forestall declining profits by attempting to recover higher labor costs by raising product prices -- say, charging $5 for a hamburger. However, consumers are not insensitive to higher prices. They would seek cheaper substitutes, thereby patronizing Burger King. The bottom line is that in the wake of higher minimum wages, surviving companies will be those that find ways to economize on labor usage.
The saddest aspect of the minimum wage story is the damage it does to human beings. The current hourly wage for a fast-food restaurant cashier is $7.25 to $9 per hour. That produces a yearly salary of $15,000 to $20,000, plus fringes. That's no great shakes, but it is honest work and a start in life. It might be the very best some people could do. Enter the arrogance and callousness of the elite. Their vision of what a person should earn, expressed by higher minimum wages, destroys people's best alternative without offering a superior one in its place.
Maybe the elite believe that welfare, unemployment compensation and possibly engaging in illegal activities are a superior alternative to earning an honest and respectable living. That is a despicable vision.
