Quote from logikos:
I don't think it is all about people lacking self control in their finances as much it is the pressure to conform with the rest of society.
Who wants to tell their children they must buy their school clothes at Target, or use hand-me-downs, when their peers wear only name brand? Or drive that beat up old car as their first car? Or no, they can't have a cell phone? Or they must share a bedroom with their sibling?
I don't really know of anybody who got themselves into debt to show off, but there are plenty who got into debt just to keep up with what they perceived as "normal".
Who eats meals as a family every night except for that once a month trip to a restaurant? Hardly anybody. Now its to a restaurant 3 or 4 times a week for dinner, out to eat at lunch at the workplace every day instead of packing a sack lunch. All these trends kill a budget.
