Many years ago, my family hosted a few Korean exchange students. They also came from wealthy families and had similar crammed schedules.

And it does get worse the older they get! I remember one of them talking about how in Korea, they would get up at 5AM so they could catch the train in time to get to school. Then after school go to a tutoring school, and then the catch the train again and be home by dark. Basically they lived at school and slept at home. At the time I thought it was fascinating because it was so different than what I knew about life, but looking back, it's a pretty crazy schedule, especially for kids.

I do have to say though, all that craziness seems to have been worth it because they are doing pretty well for themselves now and seem to be well adjusted adults.
