We don't need to read about specialization. It's enough to look at how much and what the industry produces. One airplane in two years. A serious claim to generate foreign currency for the country. If they could do something, they either have forgotten how or nobody needs it anymore. There is no progress in science, and even less in production. As much as I would like to, I can't name a single industry that would be considered advanced (of course, except for confectionery, meat and dairy, where everything is at a good level – it's all based on chemicals). So, what kind of competition can there be, especially with the West, where productivity is many times higher? All that remains is Russia, which we are trying to distance ourselves from.
And do we need to understand currency fluctuations when it's obvious that increased activity at the Euromaidan leads to a higher exchange rate for the dollar? Ask people who are buying dollars, different people, why they are doing it. The priority is political instability. And in this case, you don't need to be a super-financier; the current dollar exchange rate is entirely the merit of the Euromaidan.
