How exactly to people buy food and pay their bills in this scenario?
You're not coming off as anti-children, but you're definitely coming off as someone who lacks a basic understanding for how life in society works.
In Tech? With 3-10 times the average family income? How will they buy food if they work part time for a month or two, or one of them quits?
Probably the way as before, with their massive pay check.
Putting a family units safety and wellbeing should be a last resort solution. Major disruptions in a kids early life can have seriously negative effects on their future.
Sorry, but that is exactly how you are coming off. Your argument is basically that people with children should leave their jobs or be paid less for no reason other than that they have kids at a time when, through no fault of their own, the childcare arrangements they relied on have all been cancelled or become unreliable.
I hope I'm not coming off as anti-children but while parents couldn't have anticipated the pandemic and its impact, they need to react to the circumstances. If their home situation requires it, then they should switch to part-time or even quit temporarily.
I also agree with giving parents "extra slack", though again there are limits. At this rate the pandemic will remain with us for another year. The onus is probably in company leadership to make the necessary changes and not have colleagues start to resent one another.
