Why Did the 70's Look So Grim?

If you watch films, TV shows, or home videos from the 70's, everything looks so drab and grim, like the cities themselves were decaying, worn down, and falling apart. I can't explain it, but this kind of grim aesthetic feels ubiquitous in the 70's, whereas I don't see it nearly as much in the 60's or 80's media, which had a much more polished and clean look to them. It's why when modern films take place in the 70's, they simply cannot capture the grit and grime of the real 70's, and it ends up looking like goofy cosplay (see the movie "The Nice Guys," for example). A lot of 90's stuff has its own kind of grittiness to it that felt relatively unique to the era, but nothing compares to how grim and gritty the 70's looked, at least from the second half of the 20th century to this day.
