HISTORY: Rоbber Bаrоns Then аnd Nоw Reаd the following biography from a university course book. Bernard Madoff: A 21st-century Robber Baron 1 Bernard Madoff perpetrated the largest financial fraud in US history. His life followed aremarkable trajectory: he rose from humble circumstances and ascended to the summit ofAmerican society by building a financial empire. In 2008, after almost 50 years as chairmanof the powerful investment firm he founded, the illegitimacy of his operations was revealed.Madoff’s empire came crashing down. Billions of dollars were lost, tens of thousands ofinvestors were affected, and there were dire consequences for the global economy.   Early Life2 Born in 1938 in Queens, New York, Madoff came from a modest background. His motherwas a homemaker, and his father worked for many years as a plumber; his grandparentswere poor immigrants from Eastern Europe and Austria. Madoff’s parents were married atthe height of the Great Depression and were still struggling financially when Madoff wasborn. During his teens, his parents began to work as stockbrokers, but Madoff showed nointerest in finance at the time. He cared more about swimming competitions and working asa lifeguard. After high school, he enrolled at the University of Alabama but later transferredto Hofstra University in New York, where he studied political science.   Madoff’s Rise3 In 1960, Madoff graduated from Hofstra and founded the securities firm that made himfamous. He used $5,000 saved from part-time jobs and established Bernard L. MadoffInvestment Securities LLC, which may or may not have been legitimate in its early days.The firm promised high returns on investments and by the 1970s was attracting clients fromNew York’s most elite social circles. Eventually, the firm’s clients included director StevenSpielberg, actor Kevin Bacon, and the owner of the New York Mets baseball team. By the1980s, the firm handled up to 5% of the trading on the New York Stock Exchange. Madoffwas one of the first investors to see the value of computerized trading, which helped himdeliver unusually high returns to his clients. He came to be a key player on Wall Street, andas his company expanded, he grew ever more respected in rich and powerful circles. The Scam4 For many years no one knew it, but Madoff’s firm was being run as an elaborate Ponzischeme. This type of illegitimate investment operation takes its name from Charles Ponzi,a 1920s con man. In a Ponzi scheme, the operator—in this case, Madoff—attracts investorswith the lure of huge profits. However, the operator avoids giving specific details aboutwhere the money will come from. The operator pays his initial investors by recruiting newinvestors, then pays those new investors with money from the next set of investors, and soon. To survive, the company must have a constant influx of money; when new investors stoppaying in, the company collapses. Because no real profit exists, Ponzi schemes also collapseif many investors want to withdraw their money at the same time. Suspicion5 In 1999, the shrewd financial analyst Harry Markopolos began to suspect that Madoffwas not running a legitimate business. For almost ten years, Markopolos tried to convincegovernment regulators, the financial industry, and the media that Madoff was a fraud. Noone would listen. Then, with the dawn of the financial crisis of 2008, investors began askingto withdraw their money from Madoff’s fund. Madoff could no longer sustain his businessand confided the truth to his two sons, who were both senior employees. Madoff’s sonsreported him to the authorities, and Madoff was arrested. Harry Markopolos had been rightall along. The Consequences6 After a lengthy investigation and a trial, Madoff was sentenced to 150 years in prison.Madoff’s brother Peter was also convicted; other insiders, such as the firm’s chief financialofficer, accountant, and director of operations, are also serving jail sentences. In 2010,Madoff’s older son, Mark, committed suicide, although three years later, a London courtfound that neither Mark nor his younger brother, Andrew, had participated in the scam.More than 50,000 people have claimed to be among Madoff’s victims, and investors lost anestimated $17.5 billion. The scandal prompted widespread reform in financial regulation inthe hopes that future frauds will not go undetected. Question 1 Madoff enjoyed many years of success before his illegal operations were discovered.
