Ah, I think I detect Alan in "argument mode"!
I dunno but I feel that, say, it would be very unfortunate if Curiosity had failed due to dodgy engineering of some kind, it is something of a disaster if a building collapses due to poor design (maybe killing people) - the consequences of picking the wrong economic model might take longer to have an effect but can be far more wide ranging in those effects.
There are different scales. The failure of an engineering project or an office block might affect the individual in so small a way as to be unnoticed. A failure in the global economy has an effect on almost every single person (I am sure that there are a few people living so remotely and in such a "traditional" manner that the collapse of the entire system would go unnoticed!)
