Sorry you are talking off the top of your head when you say this:
“Plus I don’t trust that money sent to Africa will ever be used for its intended purpose”
W’s memoir goes into great detail on how it was used. Read the chapter dedicated to PEPFAR and then make your comments. The number of lives saved were estimated to be in the millions. This is not some open-ended donation of cash that was given to corrupt dictators like so much of African aid in the past was. The aid distribution is detailed beyond doubt in the chapter.
The bottom line, is we are borrowing money, or printing it, to give it away. This is unsustainable.
It’s like the prodigal son, who spent his inheritance trying to be popular - and found out that he had no more friends when he had no more money.
