Modern Day Slavery

Hundreds of years ago, slavery was very popular. One example is when the Europeans were coming to America. They used the Native Americans as their slaves but they also Brought Africans on huge slave ships and in most cases, the Africans did not make the journey to the new world. In today's society I don't think we have slavery going on like it was; working all day with no pay and poor treatment. However, I do think that we might be enslaving ourselves mentally and hindering ourselves when it comes to thinking.
In the case of the Europeans and the Africans, the Europeans realized that they needed to keep the Africans illiterate or else they might figure out how they were being treated was wrong and definitely not normal. Therefore, the slaves really knew nothing.
With that example, no one else is hindering us to learn, we are doing it to ourselves. For example, cheating. When you cheat off of someone else, what are YOU learning? Nothing. You are hindering your own self and remaining ignorant about what ever the subject matter is. Another example is the fact that we are so closed minded sometimes. Because we don't try to let anything else in besides what we already know, we miss out on many learning opportunities that we could really use to better ourselves and our knowledge.
In terms of modern day slavery, the only thing I can really make a connection with is mentally and what we actually know.
