What do you think the middle colonies depended more on indentured servants than slave for labor?

The middle colonies depended more on indentured servants than slaves for labor because of various reasons such as cost factors, availability of labor, and European labor supply. Indentured servants were relatively cheaper than purchasing slaves, and there was a steady supply of labor from Europe willing to work under temporary contracts to pay off their passage to the New World. Additionally, the middle colonies did not have the large-scale plantation economy that characterized the Southern colonies, making the need for slave labor less pressing.
