It depends on what and how you define success.
If gaining publicity raising the public awareness of the ills of Wall Street, they accomplished that to a degree. However, if you define success as changing how Wall Street does its business (poor ethics and a need to tighten regulations curbing their bad business practices), it failed miserably.
Furthermore, this might address some of the financial and institutional failure and changes that still need to be addressed:
Wall Street and the Financial Crisis: Anatomy of a Financial Collapse
Wall Street and the Financial Crisis: Anatomy of a Financial Collapse is a report on the financial crisis of 2007–2008 issued on April 13, 2011 by the United States Senate Permanent Subcommittee on Investigations. The 639 page report was issued under the chairmanship of Senators Carl Levin and Tom Coburn, and is colloquially known as the Levin-Coburn Report. After conducting “over 150 interviews and depositions, consulting with dozens of government, academic, and private sector experts” found that “the crisis was not a natural disaster, but the result of high risk, complex financial products, undisclosed conflicts of interest; and the failure of regulators, the credit rating agencies, and the market itself to rein in the excesses of Wall Street.” [
In an interview, Senator Levin noted that “The overwhelming evidence is that those institutions deceived their clients and deceived the public, and they were aided and abetted by deferential regulators and credit ratings agencies who had conflicts of interest.”
By the end of their two-year investigation, the staff amassed 56 million pages of memos, documents, prospectuses and e-mails. The report, which contains 2,800 footnotes and references thousands of internal documents focused on four major areas of concern regarding the failure of the financial system: high risk mortgage lending, failure of regulators to stop such practices, inflated credit ratings, and abuses of the system by investment banks. The Report also issued several recommendations for future action regarding each of these categories.
The Financial Crisis Inquiry Commission released its report on the financial crisis in January 2011.
