Of all the former Soviet brothers...the Ukraine is likely to be the most corrupt. You can't do business in a city there unless you bribe someone. If you want a safe construction site...you bribe someone. If you want a license of some type...you bribe someone. Thats the entire scheme of the country. While everyone may be on some anti-corruption episode and think they actually voted in a clean-cut politican...it simply looks that way...his staff and buddies are all corrupt and he just slides along the top of their efforts.
And folks say Ukraine has nothing in common with Russia.
