The Affluent Society

IDEA 1
Old ideas outlive their usefulness
Galbraith introduced the term conventional wisdom for ideas that are widely accepted because they are familiar, not because they are true. He argues that economics was still shaped by beliefs from an age of scarcity.
IDEA 2
America had moved beyond scarcity
Galbraith argues that post-war America had become an affluent society, where most people's basic needs were met. Yet economic thinking still treated producing more goods as the top priority. Thinking lagged behind reality.
IDEA 3
Production became an obsession
Galbraith criticises the focus on ever-increasing production. He argues that producing more consumer goods had become a goal in itself, even when it added little to wellbeing. More is not always better.

IDEA 1
Speculation fed on easy optimism
Galbraith describes how, in the late 1920s, many Americans came to believe that share prices would rise forever. Ordinary people and experts alike were swept up in a mood of easy optimism. That mood, he argues, made a crash almost inevitable.
IDEA 2
A land boom came first
Before the stock market bubble, Galbraith recounts a frenzy of buying land in Florida, where plots were bought and resold without anyone planning to live there. When the boom collapsed, it gave a warning that few people heeded.
IDEA 3
Borrowing magnified the bubble
Many investors bought shares on margin, paying only part of the price and borrowing the rest. Galbraith explains that this made gains look spectacular, but when prices fell, borrowers were forced to sell, pushing prices down even faster.
