Not everyone at home is not working. The biggest difference in quality of life for my working friends (and I don't have one that isn't working at least part time) is not commuting/dealing with rush hour traffic. It just adds such a layer of stress to everything. The people I know are now working online from home, some teachers are doing half time, one has resigned rather than continue to commute in to do a retail job as they can afford to do this. Others have had to get new jobs, but again, online new jobs.
The shift to online working won't affect everyone, those with jobs that have to be face to face are more likely to be min wage jobs (not all), and so it will be a source of inequity. But do I wish everyone to have to all start to commute to do jobs it turns out that entire industries can do from home- nope. And some min wage jobs can also be done from home like call centre work. One of my relatives' companies is thinking of shutting their huge offices in the city, as, although it was hard moving everyone online, it is now working great.
Good that life has shifted positively for some people- if you judge by mumsnet threads, many people were living a deeply unpleasant hectic life of commuting, driving, running into the supermarket, everything so crowded and stressful- it's natural to notice when life is not like that, even if there are worrying aspects to it, in terms of economics. Nice to get off the treadmill for a short while.
For some people, mainly I think ones with small children, life has been incredibly hard in lockdown, without their usual childcare/ways to relieve the pressure/stress and for people trying to work in that environment, it's hell. My friends who have had the worst times either live alone, or live with small kids and are trying to work. Those with mental health issues have not fared as badly as I expected, but many of those have done things on the edge of lockdown rules (e.g. seeing family from a distance, shopping daily) to get through.
