"I do not feel that post-war architecture (the iconic concrete apartment) are purely symptoms of fiat poisoning."

I guess examples that typify 60s/70s brutalist/concrete design has it's merits and perhaps answered a design brief with a view to consider a possible future. But IMO, so much of what has come and gone since then has just been a rehashing of trite ideas about what the future might be like using the materials of the day. This lack of vision, particulaly in residential architectural design, is a byproduct of maximum capacity at minimum expenditure economics, especially (contrasted with the craftsmanship found in stone and brick masonary through the ages.) A product of Cantillon's economic theory, of non-neutral money and of new money creation. I would say.
