Look at the world around you. Is there something here in our society that you don't like, that makes you uncomfortable, that makes you less secure?
Set it down. Look at it. View it from different angles. What caused it to become common? Try to imagine what would make it better, less severe, or less prevalent. Try to imagine something that would cause that change to happen, naturally and believably. That's the core of your story, or one of its facets.
Write down in a few words what happened to make that change. Did someone simply decide to make a choice? Did someone rally others to make a choice together? Did something awful happen that galvanized the community to do things differently? Or did a group of people make the same choice for wildly different reasons?
Write that down. That's the core of your story.
Now, write down either a) how someone would describe what happened to someone who hadn't been there or hadn't noticed the change, or b) the actual events that led to the change.
Either way, write about what happened after the change. How did society react to the change?
Let me know what you came up with, and maybe it'll go into the FuDis canon.
