Good for her. What did she do to help the children from the local estate who didn't bring any ingredients in at all because they didn't have it at home and their parents didn't give them to money to go and buy them?
I would like to ask you - as an adult, not as a 15 yo - what the food industry is doing to help prevent food poverty in areas where many of the basic ingredients which enable them to make such huge profits often at the expense of the health of the population, are produced by low-wage earners and their families.
Alice and my friend live very rurally in an area of large scale arable farming and horticulture where wages are low and a large percentage of the population are recent immigrants without fluent English, living in substandard housing in villages with no public transport.
Poor people there don't live 'on local estates' - there are none as city dwellers know them - they share cramped multi-family or multi-generational accommodation, and there is nowhere for anyone - rich or poor - to go and buy packets and tins at short notice without having their own transport.
So the list of shop-bought ingredients was largely inaccessible to all without significant notice at least, and all of it was provided by the school although naturally pupils were welcome to bring in their own stuff if they wished. or were able.
Poor people in that sort of area are
much more likely to have access to fruits and vegetables which are discarded either accidentally or deliberately for a range of reasons, or which are available 'for the picking' and a blind eye turned to it at least occasionally and on a small scale. Alice knew
perfectly well that the kids from the poorest families would have much easier access to that sort of stuff than to a jar of this, a tin of that, two packets of the other.
As one of the lucky ones with a mother who at least worked , albeit as a cook (not precisely a high-salary profession unless one is a celebrity cook ...), by standing up to the teacher who was clearly an entrenched townie, she was actually standing up for the poorest of the children in her class, and others who will doubtless come after her. In an area of extensive arable farming and horticulture, a bunch of basic veggies can often be picked up literally off the road- or at least off farm driveways as they exit to the road, while waiting for the school bus in the morning, or while walking home from the bus in the afternoon.
