Sounds totally grim for such a wealthy country, however you label it. I'd call it poverty, or being unacceptably poor:
Loads of sources could have been used, but here's one:
"A couple with two children living in poverty
has less than £58 per day – that’s £15 each - after housing costs to pay for food, bills, childcare, transport, household items, clothes and other expenses like school trips or children’s activities.
The same family on average income in the UK has about £96 per day – that’s £24 each - to cover these things."
