actually if hard work is put in, it's fairly simple to score 2nd
Upper and above.
and if you work smart, first class is not impossible 
Actually for me, when I see my friends scoring badly in uni, I
offered to study with them, share notes, etc... No obligations...
So what if it's a man vs man system in NUS (which is stupid)...
Everyone deserves the best if they want it...
I share my resources rather freely one...
Yes i agree with you on that... but this is life, without people
to make up the masses, it won't be that simple to get 2nd upper and
above...
Reconciling eagle's point with the OP's comments, the question
to ask ourselves or our education system is, are we rewarding
people who work their asses off to get that first class honours
(whom according to the OP goes on and makes bad decisions at work
later on), or should we be putting our focus on those with the
potential and capabilities to excel...
It all boils down to the question of innate talents/capabilites
vs. effort-derived results... From the point of view of an
"elitist", i am inclined to implore our education/scoring system to
move towards picking out the "true elites" and developing them...
How that will be done remains another question of course...
