Language is a tricky thing, words are exact and meaning is inexact.

One way to interpret this comment would be to imply the author of the quoted statement, having overwhelming advantages conferred upon them by circumstances out of their control, cannot possibly expect that their so-called "experiential wisdom" would have any applicability whatsoever to the masses for whom those same circumstances were not conferred.

If that was your intent, I do not think it serves you well.

I say that because attributing survival, much less success, to a vague notion of privilege is dismissive of an individual's agency. What is more, as a salve for the jealousy of the success for others, it really doesn't work all that well.

I have met many people who have come from many backgrounds and with their own challenges. In that time, the quality of "success" was strongly correlated with fundamentals, not with where they started.

There is a great saying, "Success makes you stupid, failure makes you smart" which speaks to the value of failing in order to better understand success, and why some succeed and others do not.

In the majority (perhaps all but I really couldn't say that as a definite) the ability to fail, take ownership of the failure and then seek the understanding to not fail again, results in success. In contrast people who fail and then externalize the reason for failure to some aspect of the situation that was out of their control and do not seek out a better way, invariably continue to fail.

Privilege exists, that is painfully obvious to me as a white male who is not habituated into getting nervous when a police officer approaches. Privilege exists in toxic organizations where friends of the boss are evaluated differently than everyone else. And privilege exists when people who conform to behavior, dress, and language norms of a group are treated differently than people who are different.

In spite of that, it has been my experience that complaining about what other people have done more easily than you did, and attributing it to privilege, doesn't actually help. Not that I'm saying you would do that, I am saying that in my life I complained about a lot of things, one was a kid my age who was interviewed by the local news station for building a robot, FROM A KIT HIS PARENTS BOUGHT HIM, as if he was some genius robot builder. Was that privilege? Of course it was, his parents could afford it and mine were trying to make sure we had some money left over at the end of the month to save for those future problems that always took money. But it didn't help me get any better to focus on him having these advantages and me having none. I befriended the owner of the TV repair shop (yeah I'm that old :-)) who would give me broken TVs and radios to take apart and learn from. I built a complete Shortwave receiver out of a couple of otherwise non-working AM/FM radios and some additional tuning components scavenged from TVs and other radios. As a result, when I got into college on a scholarship as a EE candidate I already knew the basics of how electronic circuits worked and to analyze them. The kid with the kit robot may have entered college knowing no more than how to solder according to someone else's directions.

My point is that one should not dismiss the power of one's own agency to make a better future for themselves. And I see complaining about privilege as a crutch to avoid doing the work, just like training wheels on a bike means you don't have to do the work of balancing. It is important to recognize privilege exists but it would be wrong to let it define you.
