If Sweden can encourage its own people to educate themselves to speak more than 5 languages: Swedish, German, Danish, English..(perhaps Finnish or something else), and do it such a way that they can do that from a very early age, I don't see why Singapore can't do it, and retain their various heritages.
The total focus on just the English language and Mandarin chinese, and now with younger generations not showing enough competency in both, and almost nil in our own dialects, have shown how ineffective our language policy is.
The taste of the pudding is based on the results, and the results are dismal. Should we try and stick our heads into the sand and ignore the results, or should we take stock, evaluate the results and come out with a better solution? Because this current policy on the basis of the results alone, have shown to be a failure.
A Singaporean who can only speak rojak versions of both English and Chinese these days, when the main goal was to ensure Singaporeans could speak both in international standards in this day and age is so big an obvious a gap that only people like Lee Kuan Yew can try and ignore. Too bad, he can ignore it because he has only single digits left in his own future. But Singapore will have a long way to go even after LKY is gone from this world.
Singapore's future and interests should and will not be tied to LKY's interest and future simply because this country will outlast him. We cannot follow LKY into his grave.
