Yeah, "getting Wall Street and the banks in court or sending them to jail" isn't a solution.
"Let's gather the millions of people working for commercial banks, investment banks, mutual funds, hedge funds, currency trading firms, day trading firms, online trading firms, insurance firms, etc. and put them all on trial. Which specific laws did all of these people break, you ask?... Well, we don't exactly know... but we bet they broke something."
Also, I have been providing solutions to lessen market volatility, which has been a major deterrent for companies utilizing their capital and hiring more. Stratify cap gains taxes by a higher degree- raise them on short-term trades (a very tax of say 60% for the highest income bracket(s) for day trades , 50% for a week, 40% for a month), and lower them for longer term investments (20% for a year, 10% for two years, 5% for three years, etc). I would also tax trades on commodities, particularly petroleum, at higher rates as well (as we already do with gold). The above would actually hurt much of Wall Street (there's everyone's payback), though help many others on Wall Street would benefit to such tax reform as well (guess what? our financial industry is not some homogeneous mob which operates with the absolute same goals).
Simply yelling "higher taxes" isn't a helpful solution. Intelligent solutions specify which taxes, and which rates for which brackets.
