Durability–cost trade-off and revealed preference

mechanism

Durable, repairable goods still exist, but their higher price keeps demand limited. Cheap, integrated products trade repairability and lifespan for broad affordability; repeated purchases reveal which side of that trade-off buyers actually choose.

The long-lasting television did not simply vanish. You can still buy goods built to endure—but they cost much more, and most people decline the offer.

The lifespan is inside the price

Durability requires buyers to accept a higher upfront cost. Mass-market products move the other way: integrated circuits may make a television impractical to repair, yet they also make it cheap. Producers then respond to what sells, so the market fills with goods optimized for affordability rather than indefinite maintenance.

That makes short lifespans partly a story of revealed preference. People may praise repairability in principle, but their repeated purchases show how much they will actually pay for it. This is also why Affordability as Access matters: lowering durability can be the compromise that puts a product within reach of far more people.

Where it shows up

The unrepairable television

An integrated circuit closes off component-level repair, but it also helps make the television inexpensive. The same design decision produces both the loss and the gain.

Choice is constrained by cash

A cheap purchase does not prove that someone dislikes durability; it may show only that the durable version costs more than they can pay. Revealed preference identifies the option chosen under real constraints, not the buyer’s unconstrained ideal.

Price the durable option

For your next substantial purchase, find the repairable or longer-lasting version and compare its actual price with the cheap alternative. Decide explicitly whether durability is worth that premium; if you repeatedly refuse it, stop describing disposability as something imposed entirely by producers.

Things that last a very long time exist, they cost much more, nobody buys them... integrated circuits can't be repaired but make TVs cheap — there is a trade-off and we want this.
