Let me put my thoughts first.

1. Initiate massive industrialization in the 3rd World.

2. Create as many jobs as I could.

Expected Results.

1. Massive job creation would lead to improved economy for the 3rd World, filling the gap between 3rd and the 1st World.

2. People would become busier, Literacy rate would go up, Crime and Terrorism factors will be significantly reduced.

Overall, the world would become even better and more civilized place.

No rocket science here.

PS: Bill Gates, Warren, Please don't donate money, Donate jobs.
