1. social security and insuring banks
2. market crashed from selling everything for people to get money off a false rumor
3. U.S governments placed Tarrifs on everything which is basically tax on foreign foods
4. Europe was in Debt to America after borrowing so much money so Europe could rebuild after WW1
5. Unemployment rose
6. people were dying or starving to death
7. banks closed
8. adding to number 2 people rushed to sell there stocks and even borrowed money from the bank to sell as stocks
9. banks withdrew foreign loans
10. people wanted their money from the bank
11. ALL OF THIS IS NOT IN ORDER
12. in other countries dictators rose to power
All of this is basically why it took every1 so long to get out of the great depression
