Are you freaking shitting me? Are you for real? Wall Street "works"? Since when? When was the last time that Wall St. actually added value to the overall economy, rather than sucking out all the value from it to enrich its sociopathic self, and dragging the rest of the country down with it? Have you even been paying attention to what's been going on these past few months? Although, anyone could have seen it for years prior to this meltdown.
It was the very lack of regulation--i.e. the free market--that caused this meltdown on Wall St., and thus the economy as a whole, and you actually want to use THAT as an example of where it works? That's like using the tainted Chinese milk and toy scandal as an example of how lack of oversight works.
Dude, I've worked on Wall St., at some of the biggest players. And while theoretically (and sometimes even actually), it offers value, and provides a necessary service, without which capitalism (of which there are many varieties, not all of which are laissez-faire) would not be possible in its present form--or the modern world for that matter--the more deregulated it's become, the less of a positive value it's provided the economy, and the more of a negative effect it's had on it. You want to disprove that, be my guest. But be prepared to lie.
Oh, wait, you've been doing that all along. Silly me.
You're not going to try to pull that CRA and ACORN crap on me, are you?
