Not everyone cares about the same things in the same way, with the same intensity as you do. What is important to you doesn’t have to be as important to others — and thinking it should might be something you’ll want to challenge. Your lack of interest in their concerns, and boredom discussing issues you don’t care about is exactly what you are accusing your “free-loaders” of doing. You seem dismissive and uninterested in their perspectives while wanting them to be passionate about yours.
To engage in true societal transformation requires listening to obverse perspectives, gaining support for multiple concerns, standing up to your beliefs, and tolerance. As far as going on for higher education I think you could have much to offer. Along these lines, I am reminded of the words of Nobel Prize winner Aleksandr I. Solzhenitsyn: “It’s a universal law — intolerance is the first sign of an inadequate education. An ill-educated person behaves with arrogant impatience, whereas truly profound education breeds humility.”
