Not everyone might agree but, taking a global view, I would interpret Article 25 of the UDHR [0] - right to standard of living - combined with Article 2 - right to nondiscrimination - as supporting the right to flee poverty in general. Going further, the relative wealth of countries like the U.S. is tied with exploitation and imperialistic meddling in the places where people are fleeing from, so it takes on that extra layer of responsibility. I argue that poverty is a form of persecution (exploitation) of the poor by the rich, which meets the letter of Article 14.
