This sounds like "don't go outside if you're worried about being mugged". Sorry, no we almost all pay taxes used for bailouts and have our retirements invested there by our employers. We get to criticize and advocate for change.

Please look at who got hailed out and what they were doing.

Issuing a sham mortgage is not a high frequency trade.

Most people can't do that because their money will be put there by their 401K (which if they don't put money in willl lose out as well).
