I have a couple of examples, but here's one that's close to my heart (and that, sadly, hurts my heart).
I know someone who overheard the following conversation in a workshop on global policy. In one of the tables, there was a prominent doctor and one of the richest people on Earth.
The workshop went on as normal, until at some point the discussion turned to poverty and malnutrition. The rich person asked "What do you mean, malnutrition?" and the doctor politely explained the basics of acute hunger and chronic malnutrition. At the end of the explanation, the rich person asked "How can you believe any of that?" and explained that malnutrition was made up by "envious leftists" to steal from the rich.
The doctor tried to explain that malnutrition was real, and even pulled up their phone to search for a picture of a malnourished child. When the rich person saw the picture, they said "Well, I don't know about this, but if you're hungry, wouldn't you just go to a store and buy food? If someone can't figure that out, they're just not cut out to survive".
At that point, the conversation was cut short because the workshop organizers required them to move on.
You might be wondering who this rich person was. Here's what I'll tell you: their family extracted a lot of wealth in colonial times and, since then, they have used their power and wealth to remain powerful and wealthy.
