Talking about two very different systems I'm familiar with, one in rural America one in a massive American city area. City busses were severely cut for lockdown, keeping drivers safer so ok. Now some lines are gone. Rural service recently cut because of a 'driver shortage' (offering the same starting rate as the local McDonalds). The bus comes half as often, with riders now crowded in to each bus; no more closed-off seats to keep people apart, not any more. I never read the shock doctrine, but I heard someone say 'disaster capitalism' once. Are the busses ever coming back or did we just get done?
I've got some insider knowledge because I work closely with a transit agency. Probably not, of the agencies in my region two are still severely reduced and don't have any intention to return to 2019 services and the other is on the 2019 service without any night service. I don't think the late night trains are coming back either tbh.
