Slavery had a significant impact on the Roman economy in several ways:
1. Slaves were a major part of the agricultural workforce and production, allowing large estates to be cultivated.
2. Slaves filled many roles in urban settings as well, supporting industries like mining, pottery production, and construction.
3. Slave labor kept production costs low and profits high, as slaves did not need to be paid wages. This boosted the wealth of the Roman elite who owned large numbers of slaves.
