Of course not all aid is ending, it will simply fall to aid agencies and charities to provide for the very poorest rather than governments. These aid agencies will no longer need to help out those who are getting remittances so will have more to spend on the poorest. There may even be an increase in individual donations in rich countries to provide aid when individuals realise their tax dollars are no longer being spend on aid so they may feel the responsibility to do something themselves, something that giving through the government shields us from.
