The remarkable thing is that people still do business with Goldman. Why didn't the CDO debacle undermine people's trust in that firm? Isn't this a complete failure of the market?
Brokers don't owe you shit other than not lying to or defrauding you. But people don't realize this. Brokers are salesmen, pure and simple.
Worse, now brokers often have bullshit titles that hide their nature. For example, financial advisers sound like someone who has a fiduciary duty to you, but really they are just brokers. Trying to sell you on investments.
You should treat anyone who doesn't have an explicit fiduciary duty to you as you would a car salesman.
