My article in ekspress.ee - Higher salary is not necessarily good reason for emigrating

Today, ekspress.ee, an on-line version of an Estonian weekly, published my opinion article based on my blog post from the past, modified, edited and adjusted. It presents very elementary economic analysis of the situation when two countries have very different levels of average salaries. My argument is that the higher salary abroad is not necessarily a good economic ground for emigrating (yet I don't claim that emigrating is something negative per se).
