Actually that was a problem due to the culture of stupidity and willful ignorance of risk, not some keyboard mash that caused the markets to crash.

It might be one of the rare situations where it was so bad, that after stabilizing the situation, many of the responsible parties needed to be put down.

I know from my experience working with Wachovia, the gross incompetence, system wide narrow minded greed and the fuck-everyone-but-me attitude was so bad it was mind boggling.

It was not a mistake, this was a concequence of the culture and goals of those companies.
