The market may know best, but ... ...the greedy manipulators know how to circumvent and thwart the laws, the rules, and the markets within a system that has become corrupted by the very ones it should be protecting the public from.
Also helps if you have friends in high places, especially in the USA. It explains why people like Martha Stewart get pilloried and jailed for a few thousand lousy bucks of insider trading, while the real crooks get away with scamming $billions from investors, retirees, and taxpayers. And they aren't so much as investigated, let alone jailed. Corruption rules, just be prepared to do it in a very grand way, and make sure you have the right officials and politicians looking the other way and/or backing you at the appropriate times.
The markets are no longer about investing - they are more about manoevering a minefield.
If one keeps that in mind, one just might have a chance of surviving.
