There's a little detail in the show that I always liked. They didn't shove it in your face and I appreciate the subtlety.

The detail is that there were actually very few groceries in the grocery store. If you look closely, the produce is always very low quality, and there just wasn't that much to choose from. It was a big deal when they got those navel oranges. Not much meats either, and they mostly got canned goods and such. It highlights how shitty their society is without going too overboard.
