5. Global migration goes increasingly into the shadows. There is growing evidence that limits on safe, orderly, and regular migration push vulnerable people—as many as 100 million globally —into shadowy irregular pathways. As I wrote recently, “[irregular] migration exists because there are not enough opportunities for safety and prosperity at home and too few regular means through which to remedy that lack of opportunities.” COVID-19 means that there are fewer regular means for migration than there were a couple months ago. When combined, the economic, inequality, political, and displacement-related implications discussed above will only increase desperation at a time when fewer migration pathways exist. In such a scenario, those feeling compelled to move will do so increasingly using smugglers, traffickers, and other illicit groups. Migration will be increasing in and among developing countries with weaker health systems and rule of law. Irregular migrants will travel in close quarters with other people. They will cross international boundaries without documentation or health checks. In the age of COVID-19, they will also put themselves, their fellow travelers, and anyone in their extended path at grave risk.
