1) I'd rather call the price level of their local stuff "ridiculously low". But the economic policies of Belarus is another story, and best explained by somebody from there, I think.
2) Why don't you leave it to the Belarussians to condemn their government, or not. They don't need you to speak for them. I was just stating an objective truth; compared with other countries in the region, they have less EU/global brands, and ads for it. However, if you want it, you can find designer/brand stuff at roughly EU prices, in Minsk, and a couple of McDonald's. Personally, I'd rather live in Belarus than Romania after seeing both. Despite their EU membership, Romania is in a much worse state.
As for contentment with the government and democracy, I think you'd have to look pretty hard to find anyone in Romania who thinks their government is doing a good job, or that "democracy" there is a success. And that's 25 years after they hung Ceusescu from a lamp post. The Germans re-built their entire country from rubble in less than that time - both east and west. So clearly something is a little bit off in Romania.
My point is that the Ukrainians should just bear in mind that although EU is a great peace project, it's not a ticket to economic success, as the Greek, Spaniards, Romanians, Latvians and others can confirm.
