Yes there is certainly the mis use of money.
Some people will never budget according to their income.
However, some families have no chance, parents who do not have cooking utensils, MH issues that are left untreated,
A project in Liverpool, highlighted on R4, showed some women had zero nutritional knowledge & no cooking skills, so they bought them cook books, only to find many couldn' read.
My DD did XC running at school, a seemingly cheaper sport but it really isn't, its packed full of MC parents, spikes cost a fortune, getting to training sessions and racing events, they'll never be kids from poor families there.
Lifting the 2 kids policy wont change any of this, it could be far better targeted.
