The Business Insider site has an article by Henry Blodget titled “Here’s What The Wall Street Protesters Are So Angry About…” with a chart book of information on the US’ economic disparity problem. (Of course, it’s only a problem for the 99%. The 1% wonder why everyone’s so spun up.)
It’s one view of the issue, and doesn’t get into the mechanics of what I think of “regulatory capture,” but its very solid and foundational, as far as it goes.
