It's interesting to revisit the chains that were popular when I was growing up, the ones that haven't really changed their decor or menus. The food tastes exactly like I remember it, and it's honestly terrible. But growing up I didn't know it was bad, all food everywhere basically tasted like this. It was either this or local mom & pop homestyle stuff...nothing special.
Looking back, I think I grew up at an intersection of two events: people were becoming affluent enough to eat something other than food cooked at home, and we had become so enamored with our ability to provide any season, hyper-consistent food that we never stopped to ask if it was a good idea.
Think about how many Chotchkie's-style casual dining restaurants there are, all virtually interchangeable from each other. Once you start to hit a number of locations in the hundreds, it's just inevitable.
I think foodie-ism is looking at this ossifying industry and finding it relatively easy to disrupt. It can get pretentious at times, with lists of all the locally sourced ingredients in the homemade ketchup, but it also means you can get good food for a change. It means that if you have 20 restaurants, you have 20 actual choices of places to eat and not groups of interchangeable taste-alikes.
Even in traditionally very manufactured food places, the burger joint, newer franchises like In-n-Out or Shake Shack, which actually artificially limit their expansion to ensure the kinds of ultra-high quality ingredients they use are available.
Honestly, if you like food at all, it's an awesome time to be alive, I have no idea how we made it through the 70's, 80's and 90's.
