Welcome to the real world!

Well I'm not sure how you even got into university with the level of thinking you display. Since when was societal status determined by your innate intelligence or ability beyond a superficial level?

Intergenerational barriers to mobility have been present from the second you were conceived. Richer/more educated parents have sex only when they are confident of bringing up a child in a comfortable environment where lower parents merely do it to fulfil their carnal desires. In school richer parents have always provided for more tuition and enrichment to qualify for DSA/IP programmes as well as in preparation for O and A levels. Entering the workforce richer parents again are again able to create opportunities for their children to succeed in their careers as well, mentor them as well as build an entire support network of colleagues, bosses and consultants to further said goal at the Sunday dinner.

Again, it wouldn't hurt to use a few brain cells when you're reading your next Straits Times article or whatever BS Ong Ye Kung prepares to spew about every school being a good school while extolling the benefits of the SG 'meritocracy'.
