A couple of thoughts about this:
1. Bill, you are an idiot. People are leaving Africa because of the disaster caused there by Obama ad-Dajjal and Hillary Clinton, both of whom I believe you supported.
2. Bill, you also are a scrooge. Your statement clearly indicates why the "philanthropy" of the rich is BS. You and the other oligarchs don't want to help humanity in general. You want to use your power and influence to further YOUR particular agenda, the majority of which allow the rich to continue to prosper while protecting yourselves from the hoards of unwashed, starving people clamoring to come here.
Jesus was right when he made this statement:
It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.
Matthew 19:24 KJV
Of course, I understand that Gates and the rest of the oligarchs don't give a damn what Jesus said or did, but that too is a tragedy for the USA and the world.
