You might want to read up on this. It was US economic advice which led to the rapid sell-off of public assets which resulted in the creation of the oligarchs in the first place.
Seriously, I do not need to read up on this, I was there. But one does not really need to have first-hand experience to see the deliberate deception in klein's "shock doctrine" and the like: for example, different countries in the region had markedly different timings, different implementation of reforms, different rhetoric, and different resources; but the outcomes pretty much fall into two groups: places where people demanded and expected accountability on part of government (ie. baltic states, and a few former warsaw pact countries) did relatively fine, and others devolved into oligarchies (ie. the rest of the former soviet union).
