Honesy question. How many of those peoe have kids? On my team/in my interactions with my company, the people with kids seem to struggle however the people without kids are thriving.
I've also seen a couple of people without kids really struggling due to the lack of social interaction. For most this isn't an issue, or if it is, it's not a big deal, but for some, it's really hard to replace the in-office dynamic with video calls.
The current situation is a lot tougher, though, since a lot of the things she'd normally do with the kids during the day are denied right now: the zoo is closed, museums are closed, playgrounds and parks are closed, gymnasiums are closed, no play dates with friends, no visits from family, etc.
I think it's unfair to try to draw your conclusion from the present situation.
