Poverty Causes Depression. Gasp!

As usual I can't cop a full copy of the article, but here's reference to a study by Harvard researchers claiming that low-income people have more depression than the wealthy. That's one of the biggest "Duhs" in the world. It took a study to determine this? Things must be slow in Cambridge these days--or they are just trying to find another way to restate Maslow's Hierarchy of Needs. You tell me.
