On Government Spending

The Libertarian Reader is an outstanding collection of essays, and one of my personal favourites is a piece by Russell Roberts (of Cafe Hayek) that appeared 12 years ago in the Wall Street Journal, “If You’re Paying, I’ll Have Top Sirloin.” Here’s an excerpt, in which Roberts describes “a very strange restaurant”:

When you eat there, you usually spend about $6—you have a sandwich, some fries and a drink. Of course you’d also enjoy dessert and a second drink, but that costs an additional $4. The extra food isn’t worth $4 to you, so you stick with the $6 meal.

Sometimes, you go to the same restaurant with three friends. The four of you are in the habit of splitting the check evenly. You realize after a while that the $4 drink and dessert will end up costing you only $1, because the total tab is split four ways. Should you order the drink and dessert? If you’re a nice person, you might want to spare your friends from having to subsidize your extravagance. Then it dawns on you that they may be ordering extras financed out of your pocket. But they’re your friends. They wouldn’t do that to you and you wouldn’t do that to them. And if anyone tries it among the group, social pressure will keep things under control.

But now suppose the tab is split not at each table but across the 100 diners that evening across all the tables. Now adding the $4 drink and dessert costs only 4¢. Splurging is easy to justify now. In fact you won’t just add a drink and dessert; you’ll upgrade to the steak and add a bottle of wine. Suppose you and everyone else each orders $40 worth of food. The tab for the entire restaurant will be $4000. Divided by the 100 diners, your bill comes to $40. Here is the irony. Like my neighbor at the theater, you’ll get your “fair share.” The stranger at the restaurant a few tables over pays for your meal, but you also help subsidize his. It all “evens out.”

But this outcome is a disaster. When you dine alone, you spend $6. The extra $34 of steak and other treats are not worth it. But in competition with the others, you’ve chosen a meal far out of your price range whose enjoyment falls far short of its cost.

Self-restraint goes unrewarded. If you go back to ordering your $6 meal in hopes of saving money, your tab will be close to $40 anyway unless the other 99 diners cut back also. The good citizen feels like a chump.

And so we read of the freshman Congressman who comes to Congress eager to cut pork out of the budget but in trouble back home because local projects will also come under the knife. Instead of being proud to lead the way, he is forced to fight for those projects to make sure his district gets its “fair share.”

Matters get much worse when there are gluttons and drunkards at the restaurant mixing with dieters and teetotalers. The average tab might be $40, but some are eating $80 worth of food while others are stuck with a salad and an iced tea.

Those with modest appetites would like to flee the smorgasbord, but suppose it’s the only restaurant in town and you are forced to eat there every night. Resentment and anger come naturally. And being the only restaurant in town, you can imagine the quality of the service.

That’s government. Read the full essay, it’s a classic. Also, here’s what Don Boudreaux has to say on the subject.
