Dismantling USAID has condemned hundreds of thousands of people (if not millions) to literal death through a loss of famine relief and life saving medications for diseases like HIV and tuberculosis. It has diminished the soft power of the United States, destroyed the credibility of the country for a generation or more, and didn't even save that much money. It has profited the average American not at all and likely made everyone less safe.
I have no idea what kind of person thinks that was a good idea.
Borrowing billions of dollars when you are $37 trillion in debt and giving that borrowed money to people who hate you is insane. And most of that money goes to warlords and dictators. USAID needed a complete overhaul. And do you accuse the countries who don't give aid of causing famine and death? Why just America? You are welcome to give out of your own pocket if it assuages your guilt.
