I find it interesting that it's only now, when the economy is reliant on children being in schools, is there a narrative about opening schools so that disadvantaged children can go back.
I agree, closing schools is absolutely not ideal for these students, but disadvantaged kids have unfortunately been adversely affected for the last 10 years by the government, who couldn't care less about them when they underfund schools, cut TAs, excessively focus on data, increase class sizes, focus on a narrow measure of EBacc success, and change GCSE subject syllabuses to make them completely inaccessible, or close Sure Start centres and libraries, decimate social services funding, increase tuition fees to £9,000 a year, etc.
Nobody has ever really spoken up about these issues and when they have, they have been dismissed as teachers doing the usual moaning and so these issues have been completely ignored at the ballot box.
If we're going to make this an argument now, we need to not conveniently forget it when schools are finally back up and running.
