Perhaps concentrated wealth will inspire a nation of innovative problem-solvers. But if the view of many economists is right - that it sometimes discourages innovation - then we should worry.

Hating Wall Street is an American tradition that dates back even to the days when Thomas Jefferson cursed that money lover Alexander Hamilton. And for centuries, the complaints about it have largely stayed the same: 'It does nothing! It creates chaos! It's a parasite that sucks hardworking Americans dry!'

Unlike physics, economists don't settle things. There seems to be plenty of room for different conclusions that are still accepted in the academy.

Feedback for leaders is often nuanced and difficult to deliver. That said, hearing you are passive-aggressive from 10 different people described 10 different ways becomes hard to ignore.

President Obama's decision not to go to Congress for help in establishing reasonable standards for the continued detention of Guantanamo detainees is a failure of leadership in the project of putting American law on a sound basis for a long-term confrontation with terrorism.
