Human wants are unlimited because new wants and desires are constantly emerging, and people always seek to satisfy these wants. For example, a person who has just bought a car may want to upgrade to a better model or buy a second car. This insatiable desire for more and better goods and services cannot be satisfied because resources are limited, while the wants are infinite. Additionally, resources have alternative uses, which means that when resources are used to satisfy one want, they cannot be used to satisfy another. Therefore, even if production were to increase, it would still be insufficient to meet all human wants. Ultimately, human wants will always exceed the available resources.
