I don’t think it’s hopeless, but it requires organisation to spread this understanding among people who won’t go looking for it and may be initially hostile to it. The basics of class consciousness are not that hard to grasp if presented clearly. The challenge is how to get people listening at all. You can’t just have some college-educated stranger start shouting this at people. It requires building a political movement skilfully, bit by bit, among working-class people who can take ownership of it.
