From Ponzi to Madoff
The year was 1920. The country was the United States of America. The man's name was Charles Ponzi.
Ponzi told people to stop depositing money in a savings account.Instead,they should give it to him to save
for them.Pouzi promised to pay them more than the bank.For example,a savings account might pay you
$5 a year for every $100 you deposit.Ponzi,however,would pay you $40 a year for every $100 you
gave him to hold.Many people thought this was a good plan.They began to give their money to Ponzi.
How could Ponzi make so much money for people?This is what he did with the money people gave him:
He used some of that money to pay other people who gave him money.However,he also kept a lot of the
money for himself. Soon he had $250 million.This was a kind of theft,and it was against the law.The
people who gave him their money didri't think anything was wrong.Ponzi paid them every month,just like
a bank.Ponzi continued this way of working for two years.Then one day,he didn't have enough money to
pay all the people.They discovered his crime,and he went to prison for fraud.
Ninety years later,people began to hear about a businessman in New York named Bernard Madoff.
People said he gave good advice about money.They said when they gave him their money,he paid them a
lot more than the bank.Madoff helped hospitals,schools,and individuals earn money.Over a period of 40
years,people gave him $170 billion.However,no one investigated what he did with the money.The
people who gave Madoff their money also didn'tthink anything was wrong because he paid them every
month.
One day,Madoff didn't have enough money to pay all the people he needed to pay.That's when
people discovered how Madoff worked:He was taking money from some people to pay other people,just the
way Charles Ponzi did.However,this time,instead of losing millions of dollars,people lost billions.
Madoff was accused of fraud,and the United States government officials arrested him.He didn'thave
to go on trial because he said he was guilty.In 2009,a judge sentenced him to 150 years in prison.Bernard
Madoff's crime was even bigger than Ponzi's.It was the biggest fraud in history.The lesson of this story is
clear:When something seems too good to be true,it probably is!
What did Ponzi do with the money people gave him?
A.He spent it all on things for himself.
B.He used some of it to pay other people.
C.He deposited it all in a bank.
D.He kept it all to save for a good plan.
