It's all relative.
The Ivy League graduate in your company might be the last in his or her class while
the non-ivy graduate in your company might be the first in his or her class.
Likewise, the one who waters a lot in mitbbs might be the first in his or her
class while the one never waters in mitbbs might be the last in his or her
class (but is a CEO of his or her own company).
Due to this relativity, one needs not spend too much time justifying or
attacking the actions of those who are chasing after Ivy League schools.
Live your life. Let others live their lives. Peace.
