Singapore education system doesn't work. That's why we have idiots speaking Singlish today. That's why we have racial problems today. L2 is the root of all evils and should be abolished. Every Singaporean should receive exactly the same common education, that's how a common national identity and culture can be developed and achieved, not just talked about and aspired after, but perpetually in vain as a nation divided by aspiration rather than united by pledge.
Please note before some got angry, I don't advocate abolishing Chinese, Malay or Tamil, but these should be private family affairs, teach your kids yourselves or hire tutors etc.
