Some kids are doing better because of it.
Some kids its not going to change a lot.
Some kids its not helping problems that were already there
And for some kids its the evaporation of every opportunity (even if they were already limited) they had.
It certainly isn't a blanket 'its bad for all kids' though.
I think its highlighting the difference between working families and families where there is an available parent to aid a child's well being, and children with the maturity and independence that will help them thrive in the long term (I note the younger kids in DS's year seem to be struggling far more than the older ones) as well as traditional economic divides and learning difficulties.
I also think there is a reflection of some parents' attitude to education: some believe its the sole responsibility of the state to provide and don't get involved whereas others think its a joint responsibility between state and parents. This attitude is having an impact on how parents are responding to the situation in various ways. Its making some more anxious as they feel their kids are being failed on one or both counts and its making others actively belligerant that they are being asked to do something they don't see should be their problem. Hence a range of different attitudes to the situation overall (which the kids tend to mirror).
The problem is what is the alternative?
If covid is hitting the poorest worst then sending kids to school when cases are so high and hospitals so over run, isn't necessarily a good idea either - we could be looking at a lot more people with long term sickness issues and inability to work, deaths of far more parents with school age kids and of course if the hospitals have broken there's no health care if a kid slips over and say breaks an arm.
More to the point as has been discussed before, schools were being forced to close due to outbreaks and staff shortages and kids put into constant isolation with no planned home schooling available at all (and these were disproportionally the poorest kids being affected most with reports of some forced into isolation up to 6 times between september and christmas).
There isn't an easy way out of this. Opening the schools too early is unlikely to resolve matters - indeed I strongly suspect things would be worse.
Where the problem lies is with long term resourcing in education, poor planning and support for a possible 2nd school closure (the government were adamant it wouldn't happen again and this was a foolish assumption) and long term economic inequality being such a driving force in educational inequality.
For primary age kids I don't see why any kid can't catch up academic if resources, man power and time are throw at the problem. What I see being a problem is politicians being remotely interested in enabling this. Many in government don't acknowledge the economic issues in the first place.
Its much more complex for kids in exam years. And thats where I think the problems lie most. Its not a lost generation. Its a lost age group of about 3 or 4 years primarily at A level and GCSE level. Those unfortunate to be in that group will be a microgeneration set apart from others (there is a weird microgeneration between Gen X and Millenials which have unique characteristics). This may inspire in the long run and produce some mavericks and different ways of thinking about things.
I do think that the idea that education and opportunity ends when we leave school is one which is generally unhealthy though and I do think society would do better as a whole if we were better able to see past that and work on ways to create additional opportunities in adult life. Much of our mentality about 'a lost generation' centres on this concept. Maybe, the pandemic will open our eyes a bit more on that one and force a change. Though I am not holding my breathe on that either.
