Mohammed bin Rashid Al Maktoum is Vice President and Prime Minister of the United Arab Emirates and Ruler of Dubai writes:

The basic ingredient is opportunity. Talent flows naturally to countries that create an environment for economic growth; that make life easy for enterprise; that attract and welcome investment; and that nurture a culture of achievement. Skills are attracted to challenge and possibility.

Opportunity on this scale is becoming a scarce commodity in many parts of the West. But this is not the case in the developing world – at least among countries with the appetite and determination to deploy strong governance and continually raise their competitiveness.
Second, quality of life matters greatly. A generation ago, many talented individuals would consider working outside the West a “hardship posting.” Today, standards of living in the UAE, for example, are among the highest in the world. We have shown that the business of reversing brain drain is also the business of creating a better life for citizens and residents. Building happiness is, after all, the primary business of good government everywhere.
