Why Are Iranian Investors Migrating?

The gravest danger that threatens Iran is the despair and widespread migration of human capital, Masoud Khansari, the head of Tehran Chamber of Commerce, Industries, Mines and Agriculture wrote for the chamber’s news outlet. A translation of the text follows: 
In addition to academics and scientists, many entrepreneurs and investors, who are both tired of and disappointed with the prospect of reform, are leaving the country. What is more alarming is that this trend is picking up pace among the young generation of startup entrepreneurs. You only need to ask the directors of top Iranian startups about the number of employees they have lost over the past months and years because of migration to realize the scale of the problem. 
The migration of entrepreneurs and investors should be a wake-up call for policymakers and government; this reality is a bitter pill they should swallow instead of ignoring it. They need to seek to resolve this problem. 
Why do young entrepreneurs or Iranian investors leave the country to implement their ideas in other countries? The developed and even developing countries of the world are paving the way for entrepreneurship; they encourage domestic and foreign investors to invest in their countries; they are determined to remove the obstacles in the path of entrepreneurs; they brand their country as a paradise of new ideas; we in Iran, however, are swimming against the tide.
We believe that thanks to its high capacities and by relying on young creative entrepreneurs and private sector investors, our country is capable of breaking the impasse it is currently in through detailed and purposeful planning, which impasse is the handiwork of mismanagement and external pressure.
Dialogue at various levels of the society, strong diplomacy with different countries, inviting critical views, accepting shortcomings and moving to improving the situation and delegating the affairs to people and the real private sector are prerequisites to achieving this goal.
