2. "[Congress] should insist that all derivatives trade on exchanges and in standard contracts—not in customized, build-to-suit arrangements like the ones Goldman created...the financial bailout has demonstrated that big Wall Street banks fall firmly within Washington’s regulatory authority, and regulation confers implicit bailout protection. Protected entities should not be using (potentially) public capital to run non-productive gambling tables."
3. "...Congress should take up the question of whether parties with no stake in the underlying instrument should be allowed to buy or sell credit default swaps...tax policy could be changed to skew heavily against swaps contracts that are held for short-term periods."
Lowenstein points out that Wall Street used to be a place where money was raised "for industry: to finance steel mills and technology companies." But financial products like collateralized debt obligations (CDO), which are used by banks like Goldman Sachs and have raised billions of dollars in bonuses, have really "raised nothing for nobody" but these bankers. Lowenstein writes, "In essence, they (CDOs) were simply a side bet—like those in a casino—that allowed speculators to increase society’s mortgage wager without financing a single house."
