What was the argument against slavery

The argument against slavery could be considered a lot of different things. Today slavery in the United States has been abolished and is seen as inhumane. Unfortunately, however, farther back into the time prior to the ratification of the 13th amendment to end slavery, it was a popular way for farmers in the South to make lots of money. From the very beginning, Slaves were taken from Africa against their will to work and live with their new owners in America. Slaves were considered cheap labor and they helped farmers become rich by harvesting cash crops. A lot of the farmers in the South did not care about treating the slaves properly. They usually only cared about making money. Plantation owners in the south, were primarily white, rich men, and it was not uncommon for slave owners to own more than 20 slaves on their plantation. Even following the ratification of the 13th amendment, the battle for  civil rights continued through the 1900's. It even still exists today. When people of the South lost a part of their 'Culture' they grew angry and began discriminating against African Americans which led to the creation of Jim Crow laws.The laws were used as loopholes to keep the African American's from gaining voting rights and being accepted in public and even in society as the free individuals they deserved to be. Although not explicitly written in the constitution, until the inclusion of the 13th amendment under the Bill of Rights (and others too!)  people have considered slavery as a violation of our nation's founding principles.
