Agreed.
> and because the reason for slacking is a protected one there's virtually nothing others can do about it.
Depends on who you mean by "others". When I was working and struggling, I was grateful to Google, my coworkers, and my managers for their patience with me at work. I was also angry with our society: voters and politicians who prioritized reopening @#!$@#ing bars over schools, even though my understanding was science was saying (still is saying, AFAIK) spread through the schools is relatively little and the difference to kids' learning is huge. And on parents, which is important but not as important as the impact on kids.
Our society as a whole doesn't care about young families, and it's never been so clear. There is someone to blame.
btw, I'm not sure the extent to which it is "protected". Being a parent is protected, but I'm not sure that extends to the ability to only put in half the work, even after society has failed. (And in my mind, it did fail.)
