Obviously, but try telling that to all of the world's office managers. Or try convincing college students that staying up all night to get a project done isn't going to impress anyone. Knowing what to fix doesn't mean you can implement it easily.
And so, in a weird way, pretending to be super-busy has its rewards. And this is part of why the problem even exists.
Who cares fundamentally what other students/peers are doing? Focus on yourself, your own goals/aspirations, go out and achieve it. Stop worrying about what other people think or do.
It's like saying "I've got an easy solution to HIV. Just have all the HIV+ people stop having sex or sharing needles and it'll be gone in a generation." It might be true, but you can't just wish it into happening.
