How was the situation of the slaves different from that of the column? Which one worked better?

Different strata of the population often worked in factories and farms. The main ones are slaves and columns. The labor of the colonized population was much more productive than slave labor. Despite the fact that the people of the colony opposed the dependence of their country on the metropolitanate, they were interested in labor, as it paid for and simplified their existence. Slave labor was also used frequently. But the use of such power was less beneficial, since it was unskilled labor, and besides, the slave was not paid for the work.
