The opportunities are there for hard working families who aspire for their children to do well
What about those children who do not come from aspirational families?
What about those children who have been effectively abandoned and are neglected?
I want every single child to have a good chance of making something for themselves in life. Regardless of their family circumstances. If they are written off because their families are not aspirational, then we do nothing to improve their chances.
We as a country are small and should be seeing the brightest and best children who will be our future scientists, engineers, doctors etc etc. I don't believe for one second that the coincidence of being born into an "aspirational" family makes that child better than one who is not.
That's why labours early years programme was fantastic. It was based on research which showed that the interventions needed to start very early in order to be effective. It doesn't matter that other children who weren't "poor" were also benefitting, as long as you help your target audience as well.
Now that has all been ripped up and we have the suppose holy grail of grammar schools being promised. Yet we know that by the age of 11, it is too late for those disadvantaged children. They have no chance of getting into grammar schools when it takes a shit load of tutoring - especially if they've not had a good start at primary school.
But those who support grammar schools are only really interested in either recreating their childhood (and I hardly doubt a "daughter of a vicar" was disadvantaged) or getting their little darling into a decent school.
