i certainly hope so. cuban's interesting take on wall street:

But Cuban is also proving somewhat prophetic in a much more unsettling way. In the spring of last year, only three days after the harrowing May 6 "Flash Crash" that temporarily plunged the Dow Jones Industrial Average more than 1,000 points within minutes, he wrote a blog post that seems chilling today. He titled it, "What Business is Wall Street In?" And toward the end, he wrote in bold, "There will be another crash."

"The only people who know what business Wall Street is in are the traders," Cuban wrote on May 9, 2010. "They know what business Wall Street is in better than everyone else. To traders, whether day traders or high frequency or somewhere in between, Wall Street has nothing to do with creating capital for businesses, its original goal. Wall Street is a platform. It's a platform to be exploited by every technological and intellectual means possible."

more at link. he seems to be saying that wall street is a bit of a sham that can be easily manipulated by "hacker" or big players. if that is the case, perhaps new regulations?
