This is something that’s not considered often by proponents of lockdowns and mandates. Children need social and intellectual development early on. Robbing them of those activities during crucial early years will likely have a lifetime of consequences. In truth, COVID-19 has low IFR for those under 50, and it is extremely low for minors in particular - potentially as low as 0.001%. Lockdowns are giving the elderly a few extra years while robbing the young for a lifetime. It would make more sense for the elderly to self-quarantine and let others, particularly children, go about their lives.
