For a citizen of a miserably poor and corrupt nation, their citizenship is also a problem to be solved. The surest way to help the poorest of the poor is not to send them food or money (that will likely be seized by their oppressors) but to give them a way out, some place they can go and live safely. All the existing nations are essentially closed to poor immigrants; if this works, it will be an escape valve for some fraction of the poor in poor countries as well as the rich in rich ones.
