No it doesn't. Next time you feel down or a tragedy happens, I hope someone tries this BS on you to see how you like it. A loved one dies? Well **** you for feeling bad, some guy in Vanuatu lost his whole family so your feelings are invalid. Or maybe you're one of the lucky ones that never get bothered by anything, I know nothing about you.
It's pretty well known that tactics like yours (misinterpreting statistics, telling the person they have nothing to feel bad about, shaming them for being depressed when others are also suffering or suffering worse etc) only make the depressed person feel even worse and ashamed because there must be something wrong with them.
Besides, as I said and you conveniently ignored, if you make "the grand scheme of things" grand enough, any conclusions you derive become meaningless. Such as comparing yourself to billions of 3rd-world subsistence farmers. According to your thinking, since something like 90% of the universe is made up of hydrogen gas, there's something seriously wrong with your body because it's not 90% hydrogen gas. We don't live in outer space among the stars, we live in a very special (from our perspective) part of the universe. OP doesn't live in rural China or South Sudan, he lives and works in a specific area and society on the planet. Comparing him to those places and telling him there's something wrong with him isn't helping and makes you look like a bit like the people who tell anorexics to "lol just eat something".
