There is much that can be written about slavery, but suffice it to say the statement in question is false.
Indentured servants could not marry without the permission of their master, were subject to physical punishment (like many young ordinary servants), and saw their obligation to labor enforced by the courts. To ensure uninterrupted work, female servants who became pregnant saw their term of indenture lengthened. Unlike slaves, servants were guaranteed eventual release from bondage. At the end of their term, they received a payment known as "freedom dues", and became free members of society. The contract for an indentured servant could be bought or sold, and the right to their labor would change ownership, but not the person as a piece of property.
The situation with slaves was drastically different, as they were considered as property like horses or mules. The plantation owners had complete dominance over their lives, and slaves could be punished or whipped for almost any infraction. Some plantation owners provided small amounts of food, but, for the most part, slaves grew food on small plots of land near their cabins. It was a common practice to sell family members, especially young men. No slaves were permitted to own firearms, and the penalty for having them was usually death. Many horrors were unleashed upon them, and that situation lasted until the Civil War ended in 1865.
