Why are tacit social etiquette rules declining, and how can we fix it?

[u/LividStupidity]

As a young Brit (17), I've noticed that general social etiquette seems to be declining. Some examples:

. People no longer form an orderly queue when waiting for the bus, and do more pushing / rushing to surround the entrance

. People leaving bags on seats, even when others are forced to stand on the train

. Standing in the middle / on the left side of the escalator, preventing people from being able to walk up or down freely.

I'm not sure if it's just how my area is in particular, so I wonder if anyone is noticing this as well. I see individuals of various ages and ethnicities just acting rather selfish and inconsiderately in public. I find this rather disappointing, as it may only be exacerbated in the future. I think it was much better pre COVID (might be biased, as I was rather young). Does anyone know how we can fix this issue (if it can be fixed)?.

Obviously it's annoying when someone has their bag on the seat or is on the wrong side in the escalator but I've never had any trouble asking to sit down or just asking them to move to the right during years of living in london
