> The only justification they have to be frustrated is if they expected 'enjoy middle class life' to be the normal outcome of having a job, which is the essence of privilege
That's very uncharitable and reductionist of you. Average people, no matter who they are, lead average, unfulfilled lives with unrealized dreams.
Not only are your facts wrong, as pointed out below, but reality is always more complex than that, and it's incredibly manipulative to present it like you did. Women go to university more than men, for example. You're absolutely not entitled to determined whether which of their frustrations are "justified" or not, and everybody is frustrated for a whole range of reasons all the time, not just economic reasons, but psychological, emotional, relationships, hobbies, and more. Why are white men suiciding so much? Is that a privilege?
You're not saying any of this out of empathy, as some in your cohort like to pretend. You're generalizing people by their race, essentializing them to their economic status, which dehumanizes both "privileged" and "unprivileged" completely. It's just a cheap ploy to frame yourself as righteous and "good" ("pointing it out"), and without question this fake social "science" is the biggest problem I have with the left.
