Briefly, the "financial world" is always under the more-or-less competent (these days, it's the obscenely incompetent) control of the politico-economic élite. Therefore, what you urge constitutes a nonsense, non sequitur, a thing outside the realm of human possibility at this point (there being, as yet, no such thing as a meaningfully functioning "democratically-run" society).
The markets are in turmoil, yes. But it isn't because they've been "left to their own devices." It's because, rather, they're under the control of the class of director-managers which always runs them---and that happens to have been doing a supremely stupid and inept job of it for since Reagan's and Thatcher's reign.
A "débat" including Jacques Généreux ran in the pages of Libération in the past two weeks; don't recall the exact date. Try his books. A healthy tonic for the prevailing idiocy. "In such an environment it is not surprising that the ills of technology should seem curable only through the application of more technology..." John W Aldridge
