Swiss: that's a chicken-egg problem. My hypothesis is that you've got to try to create this kind of feedback loop where you try to find some small thing you can improve in a way that's not really threatening to anybody, and have everybody appreciate in practice how that benefits them. Rinse, lather, repeat. The goal is gradual structural improvement that repeatedly demonstrates its value by improving people's lives. And you can't be dogmatic or idealistic. You'll have to do it in a way which is acceptable to existing vested interests, which will mean negotiation and giving something in return, and importantly, trying to find ways of doing things that these powerful people ultimately appreciate as being in their interest as well. That means protecting their property, personal safety, and lots more.
Special economic zones (tabula rasa), Chinese style, are an interesting way to do it. Saakashvili, for all his issues, did the unimaginable with Georgian road police and bureaucracy-busting, etc. Sustainability is the question but I suspect lasting changes remain.
