The Great Recession: Plus ca change ...
Here is a partial list:
Synthetic collateralized debt obligations (structures of credit default swaps that yield streams of income identical to payments from pools of profile-specific mortgages) have not been banned or limited to the value of the underlying loans. Thus, leveraged, non-productive "wealth" is still being conjured out of thin air;
Naked short-selling and naked credit default swaps (writing or buying credit default swaps on securities not owned by the seller or buyer) are still allowed;
Brokerage firms and investment banks are still permitted to bet against securities held in their clients' portfolios (often placed there by the very same "financial experts" and "investment advisors");
Profits in the financial system are still siphoned off into huge bonus pools rather than augment balance sheets, capital ratios, and repay the bailout money forked out by taxpayers;
Bank deposits insured by the FDIC are still intermingled with and used in derivatives trading and investments in risky assets, such as equities and corporate bonds;
Accounting rules still allow the booking of profits on hedged investments, regardless of counterparty risk (frequently the result of wrong-way risk: when the insurer is as likely to be as damaged by the insurance event as the investor) and systemic or liquidity hazards (market failures);
Compensation in the financial sector is still divorced from long-term performance. This creates moral hazard and agent-principal conflicts.
