Mitt Romney is defending his work at the private equity firm he co-founded and says it's part of why he's qualified to be president.

Romney told Time magazine on Wednesday that "someone who spent their career in the economy" is better qualified to fix the economy than someone who spent their life in politics and as a community organizer. President Barack Obama was a community organizer in Chicago before he entered politics.

Romney's response follows Obama's sharp criticism this week of Romney's record as head of Bain Capital. Romney, when pressed, suggested he welcomed a discussion of his time at the firm.

Obama said making money for investors isn't what being president is all about. He said a president's job is to worry about everybody, not just some.
