How about food production and distribution? It isn't so much third world as like shopping in the old Soviet Union. When I was a kid, you could get great cuts of delicious meat at the local butcher, bread and yummy donuts at the bakery, milk and cheese at the dairy - and this was in western PA.
There were also supermarkets springing up - bright and shiny with packed shelves and plenty of bargains. Eventually there were so many supermarkets, the little butchers and bakers and dairy stores disappeared.
It's been gradual, but I see supermarkets declining. The shelves are packed with boxes of processed stuff, but try to find a decent cut of meat, produce that doesn't look like crap or cheese that doesn't taste like plastic. Often things sell out and it is many days before it's restocked, or the products are way past their expiration date. I often have to go to multiple stores just to get all the groceries on my list. The stores seem dirty and there's never anyone who can answer a question (and you don't want to even see the people packaging meat in back or you won't want to touch the stuff!). I don't remember it being this way even 20 years ago. Is it just me, or is something happening to our food distribution?
Let me give you an example.
Once upon a time you could go to the store and buy tomatoes that were ripe, sweet and just perfect for some olive oil, salt, pepper, garlic power and oregano -- along with some good crusty French bread. Then came standardization, and the tomatoes were hard, unripe, but of a standard size. If you put them in a plastic bag with some bananas, they would ripen properly, but otherwise, forget it. Today you have to go to a gourmet market or greengrocer to get "heirloom tomatoes" that cost an arm and a leg -- but they are ripe and edible.
You might actually get a better tomato in the Third World than America, though.
