So I've been thinking about this. It's more general than social media and sardines.

There are now areas of the world with overtourism. Santorini, arguably Venice, Machu Pichu and maybe even Barcelona have more tourists than they can support. It's becoming a huge problem. Why is this the case? It's in part because people have disposable income to visit these places but I think there's a larger issue of why people want to visit these places. I think there's a FOMO element and the idea is pushed by social media in particular and media in general.

As another example, I blame at least in part the crazy NYC rent situation on Sex and the City, particularly on rents in the West Village. If you've lived in NYC you know there's so many SATC girlies living out their NYC dreams and not all of them have trust funds. You see this reflected in rents too. One side of 14th Street is Chelsea. The other side is the West Village. Rents on the Chelsea side are significantly lower than the other side because people want to be able to say they live in the West Village.

On a smaller scale you see this where people seem to view themselves as the main character in a movie or TV show and they're living out these scenes in their heads, typically to video and post online. They can be really inconsiderate about it too. Like just today I saw a video that someone in a public beach "dared" go in the water while someone was trying to get a photo of themselves and that other person got in frame. It really is main character syndrome [1].

I think what made a lot of things good in the past was lack of information (and the resultant FOMO). You've seen this in food trends too when Omega-3 became big and fish stocks suffered or when palm oil became big and that's a big problem.

Interestingly, China has a system to try and prevent everyone flocking to one or two cities ("hukou") and it's hard not to see the argument for this.

I have several triggers when I'm doomscrolling. One of the worst is when someone says "I'm trying the viral (restaurant, dish, bakery, bar, whatever)..." I've always hated this because whatever it is is never worth it. But the psychology of people wanting to show off this way is fascinating. It really feels like people's lives are that empty that they just want that external validation.

Thanks to social media, canned sardines are a scarcity on the supermarket shelf
