Notes

The shares of the stock market became over valued.
In a matter of weeks billions of dollars were lost.They were plunged into a economic crises, many businesses failed, and because the world economy was very dependent on America it effected economy around the world.
Normally, goods from businesses were bought from the public and some money went to the workers. However, because the public lost so much money,less goods were bought which means there was less payment. Without payment businesses stopped manufacturing goods, and because they didn't have enough money to pay their workers people were left unemployed.
A lot of countries around the world did something called protectionism, this was where people protected their industries by setting higher taxes for imported goods. But it lead to a collapse in international trade, countries such as Thailand and Malaysia whos main export of business was rubber and depended on america to buy them failed because America had no need for it .
