I imagine people, as soon as they understood that 1. Time is looping and 2. Everyone else is aware that time is looping and everyone keeps their memories from all previous loops. Would start coming up with ways to cope.
I mean... it's not without advantages. You're functionally immortal, and if you're lucky enough to have an okay living situation, food available for that one day, access to a shop that had whatever you wanted in stock that day, then... it could be kind of awesome? You never have to worry about money, or the long term effects of anything you do. The downside is... nobody else does either and so a lot of people wouldn't want to drive busses, open the supermarket, maintain the internet etc.
I imagine people would probably busy themselves with things like opening supermarkets to let everyone access stuff, at least once the novelty of not having to wore off... but probably nobody would care about taking money for anything, it'd be just like "yeah, help yourselves". People would probably start organising a lot of group activities for fun, like parties, sports and the like.
Because the only way to record information becomes a person's memory, being good at memorising information would become extremely important and respected. I imagine people would use a lot of mnemonic techniques like poetry to remember things between loops.
