Reasons Behind The Shift from Socially Aware Hip Hop to Gangsta Rap

I recently found this video of Wise Intelligent of Poor Righteous Teachers talking about the reasons why hip hop shifted from positive to negative in the early 90's. It's good to look back and understand the factors that have led hip hop culture to it's current state. Even though negativity is abundant in the work of many mainstream artists, I believe the amount of technology we have at our disposal has enabled one of the most fertile creative periods this music has ever seen. Every artist who wants to see hip hop shift toward more socially aware content has the ability to reach people directly and make that happen. Check out the video below. I would love to know your thoughts on the subject.
