You underestimate how sclerotic large corporations can be. I've seen people do zero work, quite visibly, at fortune 500s and not be fired for over a year.
I don't know your particular examples but likely your assessment is biased.
We always tend to think that others have it easier than us, as we do not have the full picture.

This is the very first time I saw anyone with a straight face talking about Amazon workers and mentioning "people do zero work, quite visible".
There are people at my office who haven't really done anything since March 2020 when we all got sent home. They probably weren't doing anything before then either, but at least they were there eight hours a day.
