I've gone to school in Europe and California, and I think California schools are better. Why?
In other countries they focus on memorizing facts. In the USA they focus on thinking, problem solving, working in groups, cooperating and being in a multicultural environment.
When I moved to The USA I fell in love with education, not there. My high school had ski team, drama classes, musicals, and the teachers asked us what we thought. Not in Europe. There when I entered the class the teacher didn't say a word, only pointed to the board what pages to read and write the answers. I hated education in Europe. All the homework was done in class. There were no discussions or interesting debates in any of my classes in Europe. Also, the government did not allow higher education unless there was a need for a particular profession. In the USA you can become anything you want, then the war happened in the middle east and refugees came and they didn't have enough teachers so my mom who doesn't even have any college got a job as a teacher.
The USA is like no other country, we are multicultural, and we have the best thinkers in the world. I have more than a Masters degree now and I love what I do, and I make a lot of money. As much as a doctor in Europe.
