Precisely. And you'll see parallels across other similar communities - Gujaratis, Persians, Keralites, Armenians, Jews, Punjabi Sikhs, Lebanese Maronites, Ahmadiyyas, Sindhis, Parsees and Dawoodi Bohras, etc. All communities which faced/face historical or modern-day persecution, or rampant corruption and cronyism in their original regions, but tend to do miraculously well once they leave them behind.

Either these people will migrate abroad and improve their host countries, or their home countries will grow a brain and beg them to stay behind with carrots. Lots of carrots. Like China.
