No that's just what happens to the single and childless who lose their jobs and homes.
Child poverty is more expensive and has lifelong effects which adult poverty doesn't have. We should care about all poverty but child poverty is particularly pernicious in terms of its societal consequences and children have no way of bettering their situation. Furthermore, destitute families will have to put their children in care and the cost of looking after a child in care makes furlough look cheap. Children are some of the most vulnerable members of society and are incapable of advocating for themselves - this is why a decent and humane society makes sure they are looked after.
Well perhaps you should read more threads, the theme on mumsnet at the moment is that employers should be paying their staff to babysit their own children.
I read lots of threads on mumsnet, thank you (when I should be working, but luckily I'm in charge of my own hours
!). There are one or two like you describe, but the vast majority seem to be "How the f**k am I supposed to work?". Lots of posters (including me) completely disagree with the "Well, employers will just have to flexible" point of view.
On that note, what is your solution? What do you think parents whose children aren't going to school tomorrow should do? Duct tape their kids and lock them in the cupboard?
The children exist, not much the parents can do about it now.
