- IDEA 1 OF 8
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 OF 8
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 OF 8
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.
- IDEA 4 OF 8
Investment trusts piled risk on risk
Galbraith describes investment trusts, companies that existed mainly to own shares in other companies, sometimes in long chains.
Trusts like the Goldman Sachs Trading Corporation used borrowed money to multiply their bets, and they collapsed spectacularly.
- IDEA 5 OF 8
Panic arrived in a few days
Galbraith gives a dramatic account of Black Thursday and Black Tuesday in October 1929, when huge waves of selling overwhelmed the market.
Fortunes vanished in hours, and confidence in the system was shattered.
- IDEA 6 OF 8
Bankers could not stop the fall
Leading bankers tried to calm the market by buying shares in public.
Galbraith shows that their effort worked only briefly. Once fear took hold, no group of powerful men could reverse it.
- IDEA 7 OF 8
The economy was fragile underneath
Galbraith argues that the crash turned into the Great Depression because the economy was already weak.
Income was very unequal, companies were badly structured, banks were fragile and foreign trade was shaky.
- IDEA 8 OF 8
Memory protects against folly
Galbraith concludes that financial manias tend to return when people forget past disasters.
He suggests that knowing this history is one of the best protections against repeating the same mistakes.
