In today's must-read in the Wall Street Journal, Elizabeth Warren makes the case for a Consumer Financial Protection Agency (CFPA).

The consumer agency is a watchdog that would root out gimmicks and traps and slim down paperwork, giving families a fighting chance to hang on to some of their money. So far, Wall Street CEOs seem determined to stop any kind of watchdog. They seem to think that they can run their businesses forever without our trust. This is a bad calculation.

It's a bad calculation because shareholders suffer enormously from the long-term cost of the boom-and- bust cycles that accompany a poorly regulated market. J.P. Morgan CEO Jamie Dimon recently explained this brave new world, saying that crises should be expected "every five to seven years."

He is wrong. New laws that came out of the Great Depression ended 150 years of boom-and-bust cycles and gave us 50 years with virtually no financial meltdowns. The stability ended as we dismantled those laws and failed to replace them with new laws that reflected modern business practices.

Even though boom and bust causes suffering on Main Street and is of questionable value for Wall Street - the banksters are fighting hard for it.

Now, a year later, President Obama's proposals for reform are bottled up in the Senate. The same Wall Street CEOs who brought the economy to its knees have spent more than a year and hundreds of millions of dollars furiously lobbying Washington to kill the president's proposal for a Consumer Financial Protection Agency (CFPA).

The latest bankster-funded lie is that the CFPA is more "big government." Warren lays waste to that argument:

The latest lie is that the CFPA is "big government." The CEOs all know that the current regulatory structure, which they support, is big government at its worst: bureaucratic, unaccountable and ineffective. The CFPA will consolidate seven separate bureaucracies, cut down on paperwork, and promote understandable consumer products. In the process, it will stabilize the industry, rebuild confidence in the securitization market, and leave more money in the pockets of families. Complaining about short, readable contracts and efforts to slim down bureaucracy only further diminishes the banks' credibility.

This generation of Wall Street CEOs could be the ones to forfeit America's trust. When the history of the Great Recession is written, they can be singled out as the bonus babies who were so short-sighted that they put the economy at risk and contributed to the destruction of their own companies. Or they can acknowledge how Americans' trust has been lost and take the first steps to earn it back.

Wall Street is using their money and influence to take advantage of a broken Senate to obstruct reform that's good for Main Street. Our economy needs the CFPA and we must fight for this common sense solution that will make government smaller, more efficient and better able to protect consumers.
