An expert in banking corruption and finance has joined the Bernie Sanders campaign. William K. Black, an associate professor at the University of Missouri-KC, is Bernie Sanders’ new economic advisor. Black was one of the central figures in exposing and prosecuting corruption in the savings and loan crisis from the late 1980s and mid-1990s. His addition to the Sanders campaign brings important knowledge in laws pertaining to finance and banking.

The savings and loan banking crisis resulted from a multitude of causes, one of which were two laws that helped deregulate them. The Depository Institutions Deregulation and Monetary Control Act of 1980 was signed into law by President Jimmy Carter. That law allowed credit unions and savings and loans to offer checking deposits, and to charge any loan interest rate they chose.

In 1982, Ronald Reagan furthered the deregulation of savings and loans by signing the Garn-St. Germain Depository Institutions Act, which allowed property owners to put real estate into trust accounts to avoid future lawsuits or creditors. Both bills reduced regulatory oversight and by the time the crisis was in full swing in 1995, 1,043 out of 3,234 savings and loan associations had failed due to risky and illegal behavior.

Among others, Black exposed the Keating Five, a group of five senators involved in doing favors for savings and loans in exchange for contributions. Charles Keating, the chairman of Lincoln Savings & Loan was deeply involved. Sen. John McCain was one of those senators Black exposed. He, along with the rest of the senators, was reprimanded but otherwise unpunished.

Black’s tenacity in investigating the banking corruption angered so Keating, he wrote a memo ordering his death.

“…get Black — kill him dead. If you can’t you ought to retire.”

In 1999, President Bill Clinton signed the Gramm-Leach-Bliley Act, which repealed the Glass-Steagall Act, further deregulated banking institutions in the United States. Although some economics experts disagree on whether repealing Glass-Steagall actually had anything to do with the financial crisis that devastated the economy in 2008, many agree that its absence amplified the recession’s effects.

In 2009, Black appeared on Bill Moyers to discuss the effects of the recession caused directly by Wall Street and the reckless lending of banking institutions. During the show, he claimed that these large corporations were engaging in a Ponzi-like scheme to make bad loans purposefully to “increase their own personal income.”

“All of those checks and balances report to the CEO, so if the CEO goes bad, all of the checks and balances are easily overcome. And the art form is not simply to defeat those internal controls, but to suborn them, to turn them into your greatest allies. And the bonus programs are exactly how you do that.”

Black claimed banking institutions knowingly made bad loans in order to profit from them. In 2010, he appeared before the House Financial Services Committee to testify about the role of Alt-A mortgages, or what he calls “liars’ loans” on residential real estate. These types of loans, he said, were major causes of the downfall of Lehman Brothers.

“Lehman’s failure is a story in large part of fraud. And it is fraud that begins at the absolute latest in 2001, and that is with their subprime and liars’ loan operations.”

In his column on Naked Capitalism, Black criticized President Obama and Hillary Clinton, both of whom have poor records concerning Wall Street regulation. Obama, he said, could not take money from banking felons and then pass meaningful regulations. He also criticized Clinton’s acceptance of Wall Street contributions. He supports Sanders because the Vermont senator refuses to accept Wall Street donations.

Black lambasted the Dodd-Frank bill, which he wrote “failed to mandate fundamental change” within the banking industry.

“…prosecutors he appointed lack the will to use their new statutory powers to require fundamental change. The system remains rigged because those that have the gold (Wall Street), and those that accept their gold, make the rules the rig the system and they commit hundreds of thousands of felonies with impunity for Wall Street elites.”

Sanders has also been critical of the bill, saying it doesn’t go far enough in regulating the industry.

In 2008, Black traveled to Iceland to help train and assist prosecutor and financial regulators. And although Iceland’s Prime Minister was discovered to be involved in tax havens via the Panama Papers, Black is hopeful that the small island country’s example can inspire Americans. After Icelanders took to the streets to protest, the prime minister resigned. Black expressed admiration for them.

“They know how to engage the rage. Sure it has one city and one capital — it’s easier. But the fundamental point is that they don’t put up with it.”

Black’s announcement comes at a critical juncture in Sanders’ campaign, less than two weeks before the New York primaries. It is especially important given Sanders’ lackluster interview with the New York Daily News, after which Hillary Clinton accused him of not being experienced enough to “break up the big banks.” Black’s experience in regulatory banking and law, and his ability to elucidate his points skillfully, will certainly help Sanders do the same. And perhaps Black’s position of support will help him gain more credibility with voters still wary of his economic policies.

Most of all, maybe Bill Black can help Bernie Sanders’ campaign “engage the rage,” as well.
