A new survey shows family-owned businesses are flourishing despite a sagging U.S. economy. Their resilience is part of ingenuity, part of hard work, and all in the family.
   A family business can be anything from a comer kiosk selling newspapers and phone cards to a giant corporation, like Mars, the candy bar maker, or Marriott, the hotel chain. A new survey looks at the middle ground, a cross-section of 1,000 family businesses that are at least 10-year-old, and do at least $1 million a year in business. The survey was conducted by Mass Mutual Financial Group, a group of affiliated financial services firms.
