All of these issues are interesting to dive into. The first one will lead with the society accelerating the switch to a highly digital life (think metaverse). A lot of the existing business infrastructure will go out of business when that happens, and a lot of the new infrastructure will be built to support the new lifestyle. My guess is that this will benefit the FAANG + unicorns and will hurt the SMBs.
The second one I find difficult to wrap my head around. I had no idea that someone working as a waiter has enough savings to just quit their job without moving back in with their parents - it certainly was not true for me back in the day. Perhaps that's what people are doing - moving in with their parents for the benefit of not exposing themselves to health risks? Fair enough if that's what's happening, but somehow I doubt it. The other option is that everyone just switched from one type of a low-skill career to another with less exposure (eg: hospitality to remote customer support) - except that everyone is running their call centers at low capacity these days, so what gives?
The last one is the strangest of them all. Where is the money for those extra wages coming from? Surely, there are a verticals here and there with fat margins that can easily pay more and remain profitable, but the efficient market theory would make you believe that this wouldn't be possible across all industries. And yet, the results of this survey indicate that compensation is the main driver for most people on HN. My only explanation is that the HN audience is primarily in the digital space, which as a whole has benefited from the pandemic and can pay more.
