All three lines are in real terms (after inflation). The horizontal line at $1 is where you started: anything below has lost real value, anything above has gained. Cash sat still and inflation chipped at it. Bonds barely kept their head above water. Stocks left both behind.

How we teach this
We don't sell anything.
No broker affiliation, no course upsell, no premium tier. The math is the math, and the math is free.
Decades, not days.
The decisions that actually matter don't change with the news cycle. Our horizon is the next thirty years, not the next thirty minutes.
Show, don't lecture.
Every lesson includes a working visualization. You learn by moving sliders and watching curves bend, not by memorizing definitions.
Four blocks. Each one a different question.
Eighteen lessons. Four blocks. One mental model.
