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.

Honestly, most of his ideas were either dangerous, misleading, or just plain wrong - not just in a basic sense of not matching reality, but in the much more slippery sense of being seductively appealing and rhetorically influential, to the extent they sent the West off in some very self-destructive directions.

You could make a good case for the current crisis being a perfect example of self-styled philosopher kings believing they know what's best for everyone else, while talking and thinking utter nonsense.
