If you really know Ukraine as you repeatedly claimed here and know what people are like in Communist country, you should understand what I meant. I am not just talking about corruption, I am talking about people's mindset/mentality/attitude in general. This is the reason why Ukraine couldn't pass post-communism struggle which all former Communist countries faced in 1990s.
When Ukraine became independent in 1991, it inherited one third USSR industry and many R&D centers. With it's extremely high percentage rate of higher education, huge agriculture and cheap (almost free) gas and oil from Russia, many predicted back then Ukraine would be top 10 developed country in the world in 30 years. Obviously they are wrong. Why, because Ukrainians' mindset doesn't change very much. They still stay in the mentality of 1990s.
