There's something that has become glaringly obvious to me as a working-class disabled queer person whose parents are non-disabled, not queer, and significantly more financially well off than I am (and have had a significant amount of disposable income for my entire life). Namely: there is a slice of the population, my parents very much included, whose lives and concerns are so well represented in the mainstream media, both news media and fiction, that it has genuinely never occurred to them that there could be a massive problem (or many massive problems) that they're not hearing about.
This really crystallized for me when my sister was talking about a conversation she had with our (also very well-off, mansion-owning) aunt and uncle. My sister, who's a public school teacher, mentioned feeling overworked and underpaid, which is the most common complaint I can possibly think of among public school teachers, and my uncle apparently tried to insist that my sister must be the only teacher who felt this way, or at least in a small minority, because if this were a large-scale problem, he would have heard about it. He couldn't fathom there being a big problem in his metro area that hadn't come to his personal attention.
Likewise, my mom talked to me last fall about how her department's assistant at work was having trouble finding appropriate health care for her daughter because of the daughter's specific diagnoses and needs--everywhere the assistant called said they had a long wait list, but the daughter needed care urgently. My mom insisted to me that there must be places that were both affordable and let urgent cases jump the line, because those things should exist, so in my mom's mind, naturally they do exist.
It's really hard to convey to people who are this privileged that the media leaves out huge swathes of the population and many, many massive societal problems, and that "this isn't on my radar" and "this doesn't exist" are not in fact equivalent statements. I think, at least in some cases, it's worth naming that explicitly: "Each of us only knows a small subset of what's going on in the world, and I'm telling you that this problem is real even though you haven't heard much about it until now."
I'll add that I don't think this is primarily a conspiracy by Big Media to obscure what's going on in society, at least not all the time. I think a large part of the problem is that the people with the largest media reach are generally privileged in a lot of ways, and they associate with other privileged people, which means that the concerns of less-privileged groups tend not to be top-of-mind for them. Sure, there are also efforts by editors and owners of some news outlets to deliberately mislead the public or suppress certain information or perspectives, but a lot of it also comes down to limited perspectives being self-perpetuating even without intention.
And sometimes it's useful to name explicitly that it's possible for a thing to happen without a specific person hearing about it.
