Why is efficiency a critical economic goal?

Efficiency in economics is used to refer to a number of concepts related to maximizing utility and the utilization of all resources in the process of producing goods and services. [1]

An economic system can be called efficient if it meets the following criteria:

# Nothing can be made more prosperous without sacrifice.

#No output can be obtained without increasing the number of inputs.

# There is no production without low unit costs.

#The definition will not always be the same but will generally include all ideas that can only be achieved with the available resources.

An efficient economic system can provide more goods and services to people without using more resources. In a market economy in general it is believed to be more efficient than other alternatives [2]. The first fundamental proposition of welfare is based on the provision of trust, therefore for those who claim that every market is perfectly balanced based on competition is efficient (but only exists if there is no market imperfection).
