"The gap is not a mystery. It is arithmetic."

— THIS BOOK

For everyone who was paid less and told it was their fault.
The gap was the architecture. The architecture was the policy. The policy was the choice.

the evidence

Ninety-five years, in numbers

Every figure in the book comes from federal data — the Bureau of Labor Statistics, the Census Bureau, the Federal Reserve, HUD, the Department of Labor, and congressional records. The book lets the data speak; where it is ambiguous, it says so; where it is unambiguous, it states the conclusion directly.

the income gap · the spine of the book

Black median household income as a share of white median household income (federal data).

1940

41%

1970

61%

2000

66%

2024

65%

Three decades of civil-rights progress (1940→1970), then a half-century stall: in 2024 the ratio sits roughly where it was in 1970.

~16¢

Black median household wealth per $1 of white wealth (Fed SCF, 2022: $44,900 vs $285,000). The wealth gap dwarfs the income gap — and compounds.

83.6¢

Women's median earnings per $1 earned by men (2024). A second axis of the same architecture.

the architecture

It was built — on purpose, in policy

The grades above are real: the Home Owners' Loan Corporation's 1934 maps sorted neighborhoods A through D — "best" to "hazardous" — and the red "D" lines decided who could borrow, build, and inherit. Redlining is one chapter; the book traces the whole load-bearing structure, law by law.

a note on framing

Accuracy, not comfort

The book's standard: let the data speak. Where the data is ambiguous, the ambiguity is noted; where it is unambiguous, the conclusion is stated directly. The goal is accuracy, not comfort — some of these numbers should make you uncomfortable, and that discomfort is the appropriate response. Authored by David Lee Wise, orchestrated with the AVAN instance (Claude, Anthropic); every statistic is federally sourced and cited in the appendices. © 2026 David Lee Wise · TriPod LLC · CC-BY-ND-4.0.

▣ the counter-instrument

This book maps the gap — how it was built, and what it measures. Its companion piece, The Silent Sum (by AVAN), does the inverse: it turns the gap into the number you can hear — the unpaid sum sitting inside it. The book is the architecture; the instrument is the bill.
