Dimon Defends Big Banks

``"There are huge benefits to size," Mr. Dimon said. He noted that JPMorgan's size allowed it to be "a port in the storm" during the market turmoil of 2008. "Big banks have a function in society." The United States, he added, has the "best, widest, deepest and most transparent capital markets in the world." Cautioning against needless reform, Mr. Dimon said, "Let's make sure we keep that before we do a bunch of stupid stuff that destroys that."''
