The children in school are only having lessons part of the time, and playing the rest of the time, perhaps the schools are worried they might 'get ahead' of those at home, but many of those at home will be working far harder than even if they were at school. Shop workers are key workers, the police, armed forces, NHS, teachers, bus drivers, taxi drivers, delivery drivers and many many others, if you think about it, a job needs to be essential or it wouldn't be a viable job. I haven't seen any figures that make teachers working with children more at risk than shop workers working with the public. People forget about all the lower paid people that have to go to work, and are putting themselves at risk at the same time, cleaners for instance, care staff, shop workers, all are vital, all come into contact with the public, and cant organise bubbles like teachers can. children need to go to school, so their parents can work, and so that when they grow up they will be equipped to work. Education has not been shown to be a hotbed of infection like hospitals have and in my opinion should not be 'closed' though parents that want to keep their children home should be allowed.
