I'd like to see this money used to establish a scholarship program for struggling countries. The first wave of students is brought to the US, Canada, UK, France, Japan, etc. and taught a range of subjects with a mandatory teaching course added on, the only contingency is that they return to their own (or another underdeveloped country) and remain there for a minimum duration of X years so we're not just adding a new migration path. The second wave (in say 5 years) is an in-country scholarship where this new generation can be taught by the first wave (remember 1 student /= 1 teacher, however you don't need 1 teacher to teach 1 student), those that didn't become teachers will likely be establishing businesses or supporting their local economy.
A significant portion of the scholarships should also be going to fund apprenticeships to get people certified as competent electricians, plumbers, brick layers, mechanics, etc. There's no point putting someone through university if there's going to be no one around to help build a university in their country, or their business office, etc.
One of the struggling points of our own economies is that we're vastly short handed in the skilled trades to the point that many countries (Australia) basically hands out citizenships to people with these skills. It would be asinine to play economics and screw up right off the bat. We need to educate in controlled proportions from the top and to the bottom of our own skill ladders.
I know people who are incredibly smart who can't use a hammer. Who would build their house, repair their roof, reside their property, replace their windows, etc. We're talking about regions with a high proportion of natural disasters, and they'd need a good supply of skilled workers to ensure a tragedy like Haiti doesn't happen because buildings aren't constructed to modern codes.
