Parents should be responsible for their children, but fewer and fewer are prepared to take on that responsibility.
See how much attention is paid when 'society' attempts to intervene with a child misbehaving, kicking the furniture, running round a public room, shouting, screaming, fighting, generally disturbing others when apparently under the control of its parents.
I witnessed this breakdown recently on long train journeys across England. The train service was excellent; on time, clean, comfortable, helpful staff. The only disturbance was created by out of control children, shouting, clambering over seats, running along the aisles, and more dangerously, on the platforms, without their parents making the slightest attempt to control them, and in some cases actively encouraging them. It happened on three journeys out of four; the fourth one was a very early train full of workers who actually worked on their journey and the carriages were quiet.
Reception teachers are claiming (some) young children are arriving at school totally unprepared, almost feral, spitting, snarling, eating with their hands, unable to use toilets . It is not due to covid, it is due to lack of parental responsibility
