WASHINGTON  It was billed as “Investing in America,” a live televised conversation on the state of the economy between President Obama and American workers, students, business people and retirees, a kind of Wall Street to Main Street reality check.

But it sounded like a therapy session for disillusioned Obama supporters.

In question after question during a one-hour session, which took place on Monday at the Newseum here and was televised on CNBC, Mr. Obama was confronted by people who sounded frustrated and anxious  even as some said they supported his agenda and proclaimed themselves honored to be in his presence.

People from Main Street wanted to know if the American dream still lived for them. People on Wall Street complained that he was treating them like a piñata, “whacking us with a stick,” in the words of Anthony Scaramucci, a former law school classmate of Mr. Obama’s who now runs a hedge fund and was one of the president’s questioners.

“I’m exhausted of defending you, defending your administration, defending the mantle of change that I voted for,” said the first questioner, an African-American woman who identified herself as a chief financial officer, a mother and a military veteran. “I’ve been told that I voted for a man who was going to change things in a meaningful way for the middle class and I’m waiting sir, I’m waiting. I still don’t feel it yet.”
