I don't think social or economic ideologies can exist in isolation. I think its a constant push/pull between different versions, interpretations and combinations of them, interacting, evolving, changing all the time. Some of it driven by the state apparatus, some by emergent group behavior and/or public sentiment via the participants in the local and global economy. It could just be my uneducated brain but I've always had a nagging feeling that all of this (macro-level economics and polices/programs) is a lot of hot-air and people just hand-waving exceptions away to push their own agenda.
