What were the disadvantages of the head right system?

The head right system, due to its promises of land per passenger on a voyage to America, promoted slavery since slaves were bought cheap in Africa. Because of this many planters bought slaves cheap from Africa and had them shipped to America. Also the head right system only widened the gap between rich and poor since two-thirds of those who traveled to America in the 17th century were indentured servants and could only adopts passage for themselves and their families.
