On Thursday, President Obama went to Manhattan, where he urged an audience drawn largely from Wall Street to back financial reform. “I believe,” he declared, “that these reforms are, in the end, not only in the best interest of our country, but in the best interest of the financial sector.”

Well, I wish he hadn’t said that  and not just because he really needs, as a political matter, to take a populist stance, to put some public distance between himself and the bankers. The fact is that Mr. Obama should be trying to do what’s right for the country  full stop. If doing so hurts the bankers, that’s O.K.

More than that, reform actually should hurt the bankers. A growing body of analysis suggests that an oversized financial industry is hurting the broader economy. Shrinking that oversized industry won’t make Wall Street happy, but what’s bad for Wall Street would be good for America.

Now, the reforms currently on the table  which I support  might end up being good for the financial industry as well as for the rest of us. But that’s because they only deal with part of the problem: they would make finance safer, but they might not make it smaller.
