I have a high school classmate who works in the United Nations Department of Asian Development. 20 years ago, his salary was 200-300K, zero tax. Now, I think the salary will be close to 500,000. If Musk donates 6 billions, he should supervise how they spend the money!
I suggest Musk donates this money to the Chinese government, 1) for short run, use half of the money to buy food to deliver to the hands of the people in need, and 2) for long run, spend the rest of the money to send technicians to help local people to grow rice and foods to escape poverty. This needs way more money than 6 billions.
花钱赈济饿饭的穷人,怎么花都行,就是不能交给联合国,那是个世界级超级大贪污犯的贼窝。
