It is now not uncommon for 11-year-olds to be diabetic. I see one reason for it every time I check out at my local Safeway in Washington. The candy is right there at the cash register, waiting to be eaten.
But this does not mean that the manager of the store is mean or even irresponsible. If she has qualms about this practice, she would face a real dilemma: She needs to show a profit. The margins at supermarkets are tiny. No matter what her morals, she has almost no choice but to place those sweet impulse buys where customers can see them. In other words, there is an economic equilibrium in which businesses take advantage of every opportunity to increase profits. In such an equilibrium, the candy will be at the checkout counter.
Curiously, while economists understand each and every such instance where people are tempted to buy things that are not good for them, they fail to appreciate that this occurs because of a general principle of economics. They fail to understand that free markets, as bountiful as they may be, will not only provide us with what we want, as long as we can pay for it; they will also tempt us into buying things that are bad for us, whatever the costs.
