Explanation:

An economy is a function of how money, means of production and resources (raw materials) are carefully used to facilitate the demands and supply of goods and services to meet the unending needs or requirements of the consumers.

Generally, a country's economy is largely dependent on how resources are being allocated and utilized, how many goods and services are to be produced, what should be produced, for whom they are to be produced for and how much money are to be spent by the consumers to acquire these goods and services.

Unlike the economies of the other ancient civilizations, the Roman economy was largely driven by an abundance of slave labor. In order to avoid any form of punishment, the slaves were relatively obedient to their masters and they also accepted the fate of their social position in the Roman society.

Hence, the use of cheap slave labor was predominant in Ancient Rome to the extent it reduced the level of employment for the average Roman citizens.
