Also, when would that ever not be the top category? "Things cost too much" seems like kind of a supercategory covering most of the others. Maybe "lack of money" could compete.
The top is less important than the ratio. The top 2 answers are basically stuff costs too much. Over half the people are claiming that is their biggest problem. If times were better, it still might be the top, but it shouldn't be the majority. Debt concerns, and retirement would take a bigger chunk.
