What Ohio teaches — and to whom
Ohio already requires 1 semester of personal finance for a high school diploma, a rule in force since the graduating class of 2026. That covers students still in the system. It does nothing for the adults already out of it — which, in Castalia, is most of the people reading this.
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.
Where to start in Castalia
Build a buffer before anything else
With 31.7% of Castalia living below the poverty line, the single highest-return skill here is cash-flow control: knowing what actually lands each month, what leaves automatically, and how to build even a small buffer between the two. A few hundred dollars of slack is the difference between a car repair being an inconvenience and it being a payday loan.
Get the first-decade decisions right
A median age of 29.2 means a large share of Castalia is making decisions with thirty-year consequences: the first credit card, the first lease, whether to take the employer match. These are cheap to get right now and expensive to unwind later.
