There is a lack of class analysis among normal American citizens because of the work of the three branches of the U.S. government and state. The state actually works with mainstream news platforms, so they are at fault for that in particular. What you have just explained is exactly the work of both these things. However, there are a lot of academics such as Michael Parenti (who unfortunately died recently) who have talked about this extensively for many decades, and there are many left political commentary from from leftist creators online such as Kyle Kulinksi on YouTube. Many people are having the conversations, it's just whether or not the other people are willing to let go of the narrative they been fed this whole time to have us moving in the right direction at a faster rate.
