Take a deep breath and consider what this means. Banks like JPMorgan Chase provide the banking services that allow Internet payday loansharks to exist in the first place, with the sole purpose of breaking the state laws against usury. Then Chase vultures the victims, who are often low-wage earners struggling to make ends meet, by extracting late fees from the victims’ accounts. So impoverished single moms, for example, who needed to borrow money to make the rent, get worked over twice: First they get a loan at an interest rate that would make Tony Soprano blush. Then they get nailed with overdraft fees by their loansharking bank.

For Subrina Baptiste, 33, an educational assistant in Brooklyn, the overdraft fees levied by Chase cannibalized her child support income. She said she applied for a $400 loan from Loanshoponline.com and a $700 loan from Advancemetoday.com in 2011. The loans, with annual interest rates of 730 percent and 584 percent respectively, skirt New York law.

Ms. Baptiste said she asked Chase to revoke the automatic withdrawals in October 2011, but was told that she had to ask the lenders instead. In one month, her bank records show, the lenders tried to take money from her account at least six times. Chase charged her $812 in fees and deducted over $600 from her child-support payments to cover them.

Let’s be clear: JPMorgan Chase, the big bank that supposedly is run oh-so-well by Obama’s favorite banker, Jamie Dimon, is aiding, abetting and profiting from screwing loanshark victims.

What possible justification could anyone at Chase have for being involved in this slimy business? The answer is simple: profit. Dimon and company can’t help themselves. They see a dollar in someone else’s pocket, even a poor struggling single mom, and they figure out how to put it in their own. Of course, everyone at the top will play dumb, order an investigation and then if necessary, dump some lower-level schlep. More than likely, various government agencies will ask the bank to pay a fine, which will come from the corporate kitty, not the pockets of bank executives. And the banks will promise — cross their hearts — never again to commit that precise scam again.

(Update: After the publication of Jessica Silver-Greenberg’s devastating article, Jamie Dimon “vowed on Tuesday to change how the bank deals with Internet-based payday lenders that automatically withdraw payments from borrowers’ checking accounts,” according to the New York Times. Dimon called the practices “terrible.” In a statement, the bank said, it was “taking a thorough look at all of our policies related to these issues and plan to make meaningful changes.”)

Money Laundering for the Mexican Drug Cartels and Rogue Nations

HSBC, the giant British-based bank with a large American subsidiary, agreed on Dec. 11, 2012 to pay $1.9 billion in fines for laundering $881 million for Mexico’s Sinaloa cartel and Colombia’s Norte del Valle cartel. The operation was so blatant that “Mexican traffickers used boxes specifically designed to the dimensions of an HSBC Mexico teller’s window to deposit cash on a daily basis,” reports Reuters. They also facilitated “hundreds of millions more in transactions with sanctioned countries,” according to the Justice Department.

Our banks got nailed as well. “In the United States, JPMorgan Chase & Co, Wachovia Corp and Citigroup Inc have been cited for anti-money laundering lapses or sanctions violations,” continues the Reuters report. My, my, JPMorgan Chase, the biggest bank in the U.S. sure does get around.

And the penalty? A fine (paid by the HSBC shareholders, of course, that amounts to 5.5 weeks of the bank’s earnings) and we promise – honest — never to do it again.

Too Big to Indict?

Wait, it gets worse. Why weren’t criminal charges filed against the bank itself? After all, the bank overtly violated money laundering laws. This was no clerical error. The answer is simple: “Too big to Indict,” screams the NYT editorial headline. You see federal authorities are worried that if they indict, the bank would fail, which in turn would lead to tens of thousands of lost jobs, just like what happened to Arthur Anderson after its Enron caper, or like the financial hurricane that followed the failure of Lehman Brothers. So if you’re a small fish running $10,000 in drug money, you serve time. But if you’re a big fish moving nearing a billion dollars, you can laugh all the way to your too-big-to-jail bank.

Fleecing Distressed Homeowners

The big banks, in collusion with hedge funds and the rating agencies, puffed up the housing bubble and then burst it. Nine million workers, due to no fault of their own, lost their jobs in a matter of months. Entire neighborhoods saw their home values crash. Tens of millions faced foreclosure.

The big banks, which were bailed out and survived the crash, sought to foreclose on as many homes as possible, as fast as possible. Hey, that’s where the money was. In doing so they resorted to many unsavory practices including illegal robo-signing of foreclosure documents. When nailed by the government, the big banks agreed to provide billions in aid for distressed homeowners. Were they finally forced to do the right thing? Not a chance. (See “Homeowners still face foreclosure despite billion in aid” NYT 2/22.)

The big banks, despite what they say in their press statements, found a convenient loophole in the government settlement. The banks began forgiving second mortgages, and then foreclosing on the first mortgage. That’s a cute maneuver because in a foreclosure, the bank rarely can collect on the second mortgage anyway. So they’re giving away something of no value to distressed sellers and getting government credit for it. Just another day at the office for our favorite banksters.

The Indictments Go On…

I could write a book about all the ways in which banks and their hedge fund cousins have turned cheating into a way of life. (In fact, I just did: “How to Earn a Million Dollars an Hour: Why Hedge Funds Get Away With Siphoning off America’s Wealth. Here’s the AlterNet interview. )

JPMorgan Chase, Citigroup and Goldman Sachs have been fined over a billion dollars for creating and selling mortgage-related securities that were designed to fail so their hedge fund buddies could make billions. And then we’ve got the recent LIBOR scandal where the biggest banks colluded to manipulate interest rates for fun and profit.

It’s not about good people or bad people running these banks and hedge funds. It’s the very nature of these institutions. That’s what they do. They make big money by doing what the rest of us would call cheating. As the record clearly shows, they cheat the second they get the chance.

What kind of institution would loanshark, money launder, fix rates, game mortgage relief programs, and produce products designed to fail? Answer: An institution that should not exist.

Nationalize Now and Create State Banks

There are about 20 too-big-to fail banks which have been designated “systematically significant.” These should be immediately nationalized. Shareholder value should be wiped out because these banks are repeatedly violating the law, including aiding and abetting criminal enterprises. All employees should be placed on the federal civil service scale, where the top salary is approximately $130,000.

Can the government run banks? Yes, if we break up the big banks and turn them over to state governments so that each state would have at least one public bank. (North Dakota has a strong working model.) The larger states would have several public state banks. But never again would we allow banks to grow so large as to threaten our financial system and violate the public trust. Let FDIC regulate the state banks. They’re actually good at it.

(We’d also have to do something about the shadow banking industry — the large hedge funds and private equity firms. Eliminating their carried-interest tax loophole and slapping on a strong financial transaction tax would go a long way toward reining them in.)

Won’t the most talented bankers leave the industry?

Hurray! It can’t happen soon enough. It’s time for the best and the brightest to rejoin the human race and help produce value for their fellow citizens. Let them become doctors, research scientists, teachers or even wealthy entrepreneurs who produce tangible goods and services that we want and need. What we don’t need are more banksters.

Isn’t This Socialism?

We already have socialism for rich financiers. They get to keep all of the upside of their shady machinations and we get to bail them out when they fail. This billionaire bailout society is now so entrenched that our nascent economic recovery of the last two years has been entirely captured by the top 1 percent. Meanwhile the rest of have received nothing. Nada. (See “Why Is the Entire Recovery Going to the Top One Percent?“)

I know, I know, people say, “Next time, just don’t bail them out!” Meanwhile, they get to rip us off, day in and day out, until the next crash? No thanks. Put them out of business now. If you have a better idea, let’s hear it.
