Ok so I get it. Some people are better than others. Scrolling down certain profiles it is obvious that some have a very opulent lifestyles. Photographs of them exploring exotic locations Vegas, Bali and Dubai. Countless new bags, watches, shoes, trainers, vehicles and whatever cosmetic device. Photographs of their very good-looking, status-rich friends and their highly desirable significant other.
It's narcissism, no doubt. It is very much someone telling you "I am better than you" but on a mass level. If they can somehow convey that message to thousands of followers, they will do it.
This is where it gets sick. My issue with Instagram is the feet. There are countless photographs and videos where a person, somewhat bizarrely, seems determined to include their feet. It's usually their feet with some kind of magnificent backdrop, like a landmark, one of their whipped friends or I'm guessing a snapshot of their new boots they uploaded right after burning someone of their outer circle. I actually do not think this is the lustful foot fetish that seems to occupy 90% of the internet, I think it is narcissism, again. The person is saying they're better than you by including a photograph of the lowest part of their body. Where you belong, no doubt.
