What is a leftist worth? And the extreme convenience of the "oppressed narrative"

A teacher typically defends their own interests as a member of a professional class on whose behalf they "act." That is, fundamentally, what it is. But it is highly convenient for them to adopt a narrative that not only elevates them to a symbolically superior position of social importance, but also links the defense of their own interests to those of the disadvantaged classes. This is extremely convenient, as it implies that they are also championing the interests of the poor. However, actions speak louder than the mere defense of vague rhetoric. And these actions reveal that the majority of the "educator" class—whether in Brazil or the U.S.—are primarily concerned with their own interests. They are just as petty as any other human group. Furthermore, they consider themselves vital to society (there are several "sensitive" points that call into question this belief—a very popular one among them—which I have addressed in other texts). As I have noted before, if a "far-right" party were to advocate for a massive salary increase for them, one shouldn't be surprised if the majority changed their ideology overnight. At their core, they are perhaps no different from mercenaries—or, for that matter, prostitutes. They sell themselves to the highest bidder. Yet, having a narrative that preaches "love" and "solidarity"—in the most cynical and ill-intentioned way possible—can serve as a wonderful moral shield, especially when one’s own character flaws and poor judgment become apparent.
