Who Are the Biggest Defrauders of the US Govt.?

Between 1990 and 2010, US spending on prescription drugs rose from $40 billion to more than $230 billion annually.
A 2010 study analyzed trends in criminal and civil actions against drug companies, and revealed that the drug industry is the biggest defrauder of the federal government under the False Claims Act. Despite stiffer financial penalties, criminal activity has increased dramatically in the past five years, indicating that criminal prosecution of company leadership may be needed to quell unlawful behavior by the pharmaceutical industry.
The worst of the worst are GlaxoSmithKline, Pfizer, Eli Lilly, and Schering-Plough. These four companies accounted for 53 percent of all financial penalties imposed on pharmaceutical companies between 1990 and 2010.
Last year, the Bureau of Investigative Journalists also highlighted the vast ongoing corruption within the pharmaceutical industry. Many pharmaceutical companies are repeatedly found guilty of fraud, cover-ups of fatal side effects, paying huge kickbacks to doctors, and manipulating scientific research.
A total of 19 drug companies also made AllBusiness.com’s Top 100 Corporate Criminals List for the 1990s.
