Can you imagine if the frown turned into a smile upon hearing that? That's the true depressing thought (that we would take pleasure in hearing of others misery).
Yes, taken to the logical conclusion the only person who can complain about their station is the one person who has it worse than anyone else in the world.
For a few people, this kind of thinking helps. It does for me, actually. When I feel like my life sucks it can help to compare myself to an imaginary Anglo-Saxon peasant woman during the invasion of the Sons of Lodbrok, and it actually helps to realize just how much better I have it than her.
But that doesn't work for everyone, and even those it works for kinda need to do the comparison themselves, not have it pushed on them.
It can also make a person feel worse by making them feel like they're a bad person for daring to have depression when there are others who have worse lives.
For me, I feel depressed thinking about how bad things are for so many people, and knowing there's nothing I can do to help. At least not in any significant way
I compare myself to a farmer peasant, and think about how I have more cool tech I can't afford but in exchange peeling skin and bloody poop and honestly probably no area of better health.
