They should invest in maths teaching, by all means and/or do more to teach kids the practical applications in finance management (interest, taxes etc), which is something I see people ask to be taught time and again.
But I don't see what they're supposed to teach? If kids don't have the basics, it's no use teaching them advanced maths; if kids have the basics, they don't need teaching them that; and some kids (like me) are OK at GCSE but have no interest or ability in advanced mathematics, and it's not of any use to the vast majority of people.
It's just saying something to make red-faced old men go 'Quite right, young people need to do more hard subjects!'
