> This logic is akin to forcibly beating someone with their own hand and asking "why do you beat yourself". When the best people leave then it's blindingly obvious they aren't available to fix domestic politics, isn't it?

I type this reply from my home office in Estonia, Northeastern Europe. I did witness massive brain drain before 2003 when Estonia joined the EU, and I have many (some are exceptionally well educated) friends who left the country afterwards. Just recently a very well educated young neurosurgeon I know made the decision to leave for pursuing the postgrad in Canada and then Switzerland, both countries outside the EU (oh snap, "bad EU" is not guilty this time). Should I blame Canada for a local provincial academic/research landscape? How can I punish them, maybe cheer for some of their trade block to collapse? Pathetic.

I'd rather double-think about my domestic electoral preferences and what can I personally do to transform my country so that more people (many already do) would consider returning. I don't follow who's forcibly beating Eastern European countries with their hands and how exactly: people move all the time in all directions for better opportunities. That's how it is, people move from Finland to Sweden, from Sweden to Norway, from Norway to Germany, etc. It's fine. It provides a much larger landscape of opportunities for different population slices. The EU has made this movement much easier, but Estonians supplied Finland with labor well before joining the EU. Today Russia/Ukraine/Belarus does the same to us, if you're entrepreneurial enough to take advantage of it.

At the same time, English is the main working language in a massive number of local technology companies[1], incl. Pipedrive, Transferwise, Starship Technologies, foreign offices of Twilio, Skype, etc. You meet well educated people from all over the EU (a lot of Spaniards, Portuguese, Swedes) and outer world (from Russia to Brazil) in the foyers of these offices. For some reason they reach Estonia with mediocre salaries by DE/SE/NL and even FI standards. Apparently, you being a tiny Eastern European country, still able to compete for talented brains, if you actually make efforts. So do efforts, don't look whom to blame.

> And as eastern europe does not have colonial past, there isn't large pool of brains that know local language and can be drained from third world to replace people who left.

LOL so what? The most ridiculous excuse I've heard. You don't have colonial past, but you have a pretty huge open bloc of well educated people all over the EU. Compete for them! And yes, this may require adjusting language and cultural requirements, just as Amsterdam is a booming international hub and pretty much an English speaking city today[2][3]. People don't learn German, Dutch, Finnish and Swedish overnight, and it's more often not really required.

> I think it's in interest of whole EU that best people stay in their countries. Instead of just sending money via cohesion funds, it should think about creating local opportunities for them.

No doubts in that, fully agreed. But it's not EU's obligation to supply your country with profitable enterprises and (say) Polish-speaking citizens. You have to make efforts to achieve this, not seeking to destroy the union for everyone else, because you couldn't.
