Then I assume that you read the article.
Does it not intrigue you that it appears in American Banking News?
It is not like it appeared in the Enquirer.
Yes, money and banking is complex.
That is why it is screwed up.
It needs to run on the KISS principle. Mostly, simple non-complex things work better than complex.
And much easier to fix when broken.
Yes, it does. And I noted their open-mindedness.
But then Buffet is an unreformed Leftist, too.
As for complexity, you describe some kind of a world that is both Utopian and static. It is Utopian because your picture assumes that society is uniform. It is not. A day-trader with high-school education may find certain things complex while a math wiz at an investment bank may find that same thing elementary. In addition, what is complex today often becomes simple tomorrow (think of the flat Earth, for instance).
The present-day crises has little to do with complexity. It is a result of social engineering by Congress (mortgages), aggravated by stupid regulatory restrictions (mark-to-market and lax leverage).
