Do you have evidence of how many children are affected for life from having to stay at home with their family most of the time for a few months? And what model are you using for projecting lifetime effects, given the pandemic only ended a few years ago?
Compared with counter evidence, e.g. the number of children who would have died or been affected for life if they (or their parents/siblings) were unable to access urgent medical treatment (for any injury, ailment or disability) if hospitals became overwhelmed?
Also, is your evidence on after-affects because of lockdowns per se or because some (or perhaps most) people have struggled to return to the intense and demanding lives they lived pre-lockdowns, having got used to a gentler, less scheduled pace of life with fewer demands? Have you also factored in the mental health affects on children who were instilled with fear by parents during the pandemic?
As PPs have already said, it was only the privileged who experienced the safety of lockdowns. Thousands of people (healthcare staff, cleaners, delivering workers, transport workers, supermarket workers) did carry on with their lives just as they used to, working outside of the home, with their children continuing to attend school. In many cases they died from COVID or had their health (including mental health) severely compromised by its impact. Some had to continue because otherwise they had no money for rent or food (e.g. people with No Recourse to Public Funds). So they worked even when infectious.
