Unlike in the United States of America, Great Britain was able to ban slavery without violence. This horrendous practice was removed with help from logic. The prior era of the Enlightenment reasoned that all men have equal rights, and seeing that slaves are humans too, they should share our rights and not be enslaved. Unfortunately, this argument convinced few. A better argument against slavery was efficiency. Slaves required food and housing year round, even if their product was seasonal. Additionally, someone who is being forced against their will to do something will be decidedly unmotivated, lazy when possible, and cut corners often. The worker doing the same job for money will strive to do his best, be as efficient as possible, and produce higher quality products. Also, the paid worker needs no food or shelter and can be hired when desired. The common thought about slave ships was that the sailors working them were being trained and could be pulled into the service of the monarch as a navy sailor. This was, however, disproved by abolitionists. The truth was that the conditions on the slave ships were actually killing the sailors. Combine those facts with the rise of the machine and factory and the corresponding decrease in necessary labor, and no wonder slavery was banned in Britain. The British slave trade disappeared without violence because of Enlightenment ideas and simple logic.
