Why should slavery be abolished

Slavery started because white people decided that they were better than everybody else. This has been an issue for long time, where if someone looks different than you they must be inferior.

Slavery should be abolished because it's going against a basic human right, to be free. Treating people like animals isn't okay. People should be payed fr their work and be treated respectfully by their bosses. The should be free to go home and do whatever they want after a hard day of labor.
