As someone who also lives in a country heavily affected by brain drain, I put in very high regard the freedoms enjoyed in those countries you choose to ignore, because it's the lack of them that causes the brain drain.

Skilled professionals and investors are reluctant to invest their time/money in a country that taxes the crap out of them without giving much back. Excessive protectionism and high costs of living punish the people that can move the country forward just to prevent stagnant industries from suffering an inevitable blow for a little longer.
