If you are still unclear about socialism, what it is, the ideas behind it, why it’s good or bad; then here is another video from Professor Richard Wolff to help you out. Few people of our times, in my mind, break things down easier than the good professor.
This is by no means a video to make any of us an expert, but rather an excellent overview that clearly describes the ideas, history and mistakes of socialism in the 20th century. It should peak your curiosity to explore more if you feel capitalism is a failed system or if you just feel things are unfair in the modern world.
If you love capitalism, I suggest you listen as well. There may be things you weren’t aware of or maybe you’ve misunderstood what socialism actually is.
