Matt Taibbi of Rolling Stone sharply questions the integrity of the stock market:

Virtually every week now we see stories like this that hint at a kind of two-tiered market system – in which most of the real action takes place inside an unregulated black-box network of connected insiders who don’t disclose their relationships or their interests, while everyone else, i.e. the regular suckers, live in the more tightly-policed world of prospectuses and quarterly reporting and so on. . . . Sooner or later, people are going to clue into the fact that one or two big banks, acting in concert with a choice assortment of unscrupulous “preferred investors,” can at least temporarily prop up or topple just about anything they want, from Greece to Bear Stearns to Lehman Brothers.
