I love this animated illustration that my friend Agnieszka helped create for Norton Sociology. It is narrated by sociologist Dalton Conley who is the author of You May Ask Yourself: An Introduction to Thinking like a Sociologist. This video explains the concept of social stratification.

Interesting stuff! I have always loved sociology and especially how these concepts help us understand the communities that we live in. One of my favorite things about Star Trek was how it was able to explore different societal structures and see how different models might play out and what problems might present themselves. There is no perfect society. There are always problems. But I find it very interesting to consider different ways of doing things and how that might affect the world that surrounds us.
