I'm sorry, this seems a bit disconnected with the reality of actively working and simultaneously taking care of children. If you are working from home, there may be absolutely no or very little time to give quality instruction to children. Anecdotally, at the start of the pandemic, I was in a surgical residency. My specialty (otolaryngology) was locked down pretty hard across the nation, so I actually was at home a lot during the start of the pandemic, as there was a big scare about risk with routine ENT encounters and surgery. My wife worked in HR and was totally working from home.
For the first two months, I did most of the child care despite being in a busy surgical residency. Our children were about a year old and required a lot of active watching and caring for them. My wife may have been able to step away and change diapers and feed (sometimes she would be tied up). There was certainly no time to give quality education.
To give quality rearing and education to children while working would essentially be the equivalent of working two jobs. Working from home does not necessarily mean you log on, sit at home, and then go about your day as you like (i know some may have been able to do that, for better or worse). I'm not sure why you are insisting that parents taking on this extra burden while working (from home or not) is an unreasonable explanation for this.
