A deadweight product is a good or service that has little to no value or purpose, and therefore creates a burden or weight on the economy or society. These products are often considered unnecessary or obsolete, and can result in wasted resources and lost opportunities. Examples of deadweight products include outdated technology, overpriced luxury items, and excess inventory. In contrast to essential goods and services, deadweight products do not contribute to the overall well-being or progress of a society, and can ultimately hinder economic growth.
