I grew up in Eastern Europe and your statement regarding "the elevation of hustle and cunning above all other forms of intelligence" rings so true and brings back memories. When I grew up, being able to criminally take advantage of other people and the state was revered as a highly desirable trait. I suspect that any behaviour that leads to monetary success in a society, will slowly become admired, regardless if it's ethical or not.
If it's any consolation, that's what happens to any highly corrupt country. People skirting the rules, from avoiding taxes to outright theft are called smart and others who don't are called wankers.
