INSIDE
A RIGGED ECONOMY
Economic inequality
is higher in the U.S.
than in virtually all other
advanced countries.
The American political
system, coupled with high
initial inequality, gave the

restoring hope.
AUTOMATING BIAS
Politicians and program

But without addressing

entrenches inequality.
THE HEALTH-

Inequality leads to poor
health and early death—

care and nutrition.
A wider gap between rich
and poor increases wear
and tear on body parts
through chronic stress,
recent research shows.
Such psychosocial stress

A greater gap in a given
place between those with
and without economic and
political power drives greater
environmental damage there.

HIGH ECONOMIC INEQUALITY NEGATIVELY IMPACTS NEARLY EVERY ASPECT OF HUMAN
