I would take studying in quotes: "studying"
Because they do not actually earn any useful or marketable skills during those almost ten years.
My wife told me this is called academism.
There may be some pressure for this, but in most high schools in America it simply isn't needed. You can get A's and B's mostly by showing up if you are reasonably intelligent. Even getting all A's wasn't that difficult.
but getting into college isn't hard either. Unless you are shooting for Harvard it's just not. They are businesses that like to make money. They want to take your money.
