What New Jersey teaches — and to whom
New Jersey requires a half-year of financial literacy in middle school rather than a high-school graduation course. Which means for most residents of Mendham, whatever they know about money they picked up somewhere other than a classroom.
LearnLife organises this the way the decisions actually arrive: Money — budgeting, credit, debt and taxes — the mechanics nobody is formally taught; Legal literacy — leases, contracts, employment rights and what a signature actually commits you to; Emotional regulation — the self-management that decides whether the other skills ever get used.

Shift from accumulating to drawing down
