Anything to do with economics or money falls at the first hurdle, because economics and money are primarily political - which is to say they're about power for its own sake, and not about the common good, or social improvement, or reality-based decision making, or any of those other fine things.

After a token start in engineering - with management and social science - Trichet's education was almost entirely political, so I'm not sure why you think he's a technocrat. (Being labelled as such in the press hardly counts, of course.)

A true technocrat would have spent a significant part of their career building stuff that works and/or doesn't fall down. Most of the so-called technocrats have never come close to this - with predictably hilarious consequences.
