The base rates nobody budgets for

Every financial plan in this curriculum has quietly assumed a household that stays roughly intact: income continuing, health holding, the family unit stable. This closing track begins by pricing that assumption honestly — because the events that break it are not lightning strikes. Job loss, medical crisis, divorce, and disability are base-rate ordinary events — each with lifetime odds that make "it won't happen to me" a statistical error, not a plan: BLS data shows roughly 1.1% of all employment ends in a layoff or discharge in a typical month;1 SSA data finds roughly 1 in 4 of today's 20-year-olds will experience a disability lasting a year or more before reaching retirement age;2 divorce remains common, though the widely-repeated "50% of marriages end in divorce" figure is a demographic oversimplification (it compares unrelated annual marriage and divorce rates rather than tracking real couples over time) — careful cohort-based estimates run lower and have been declining;3 and how much medical debt contributes to bankruptcy is itself a genuinely disputed research question (one widely-cited estimate put it near 62% of filings, a more recent quasi-experimental study found a meaningfully smaller share, and the original researchers have disputed that finding in turn)4 — but medical bills are, at minimum, a recognized contributor to a meaningful share of bankruptcies.

Optimism bias (Optimism, Restraint, and the Cost of Compounding) is the wiring underneath: bad outcomes are real, acknowledged — as things that happen to other people's households. The insurance industry prices these odds daily (Protection exists because the risks are real enough to underwrite); the planning failure is that households insure some tails while planning as if none exist — buffer sized for car repairs, not for six months of no income; obligations sized to two incomes with no thought experiment for one.

What the base rates change

Not pessimism — sizing. The events' ordinariness is exactly why they belong inside planning rather than outside it: a risk with double-digit lifetime odds is a design input, not an act of God. The practical outputs, built through this track: exposure sized honestly (15.2), the system's actual machinery understood before it's needed (15.3-15.7 — because learning bankruptcy law or unemployment mechanics during the crisis is learning underwater), and the rebuilding path known (15.8 — because knowing recovery exists changes crisis decisions in real time). Preparation's honest limit is this track's title: sometimes the shock exceeds the buffer, the insurance, the plan — and what remains decisive then is sequence knowledge: what to do first, what to protect, what to never do. That knowledge costs nothing to hold and everything to lack.

The takeaway

The household-breaking events are base-rate ordinary — common enough to underwrite, common enough to plan for. Price them as design inputs: size the real exposure, learn the machinery calm, know the recovery path — because "it won't happen to me" was never a plan, and the households that navigate these events best are the ones that knew the map before they needed it.

  3. The "50% of marriages end in divorce" figure divides unrelated annual marriage and divorce rates rather than tracking real cohorts over time, a methodology demographers reject; CDC/NCHS cohort-based data shows lower and declining divorce trends.
  4. The medical-bankruptcy contribution question is a genuine, unresolved research controversy: Himmelstein et al.'s widely-cited estimate puts medical debt's contribution near 62% of filings; Dobkin, Finkelstein, Kluender & Notowidigdo's 2018 quasi-experimental study (New England Journal of Medicine) found a meaningfully smaller share; the original authors have disputed the newer finding in turn. Both figures are presented here as contested rather than either being asserted as settled.
