When a manufacturer wishes to profit from a product that is necessary to the consumer, but (the product) is liable to malfunction, break, or otherwise cease to remain useful- and the consumer is expected to purchase the same product over and over again... i.e. Pencils, Cheap Headphones, Batteries, Poorly Constructed or Poorly Engineered Products. What is it called when the consumer partakes in this cycle (usually unwillingly / unwittingly) ?
