Musk spent 100 million to build a private elementary school
This is a school established to train Musk's favorite youngest son. It is said that only 21 children are enrolled. This is an elite training model among elites.
It has become a tradition for American rich people to donate to build schools. Famous schools in American history, such as Stanford, Harvard, Yale, and MIT, were all founded by private individuals.
But elementary schools like Musk's that only enroll 21 people are relatively rare. I guess as Musk's son grows up, he will also open a middle school... But I remember that Musk's son was trained by private tutors at home...
