The New York Times had an article on the Middle East peace plan being developed by Donald Trump and his son-in-law Jared Kushner. The piece tells readers:

"The idea is to secure financial commitments from wealthy Persian Gulf states as well as donors in Europe and Asia to induce the Palestinians and their allies to make political concessions to resolve the decades-old conflict with Israel. The White House has indicated that it is seeking tens of billions of dollars but would not identify a precise figure; diplomats and lawmakers have been told the goal is about $68 billion for the Palestinians, Egypt, Jordan, and Lebanon."

This is obviously quite vague, but it might be helpful to readers to put this $68 billion figure in context. First, it is a bit more than half of the estimated fortune of Jeff Bezos.

More importantly, if we take the total population of the four groups listed, it comes to roughly 120 million. This means that the sum that Trump and Kushner hope to raise to induce a commitment to their peace plan comes to $560 per person. This seems to be a one-time figure rather than any ongoing commitment of aid.
