Hey u know old fart to paraphrase a chinese saying in english. He says 1 who dares to say 2?
His words are the gospel truth. How could the citizens of sg, whom are peasants to him, ever hope to challenge his knowledge and wisdom?
So when he says sinkees are not smart enough to master a few language well he is right.
The next thing about switzerland. Yes they can speak a few languages. In the US ppl learn spanish along with english yet the point is these languages belong to the same family. English and german are in the same germanic branch, french and spanish are romance languages and all are classified under indo-european.
Now take chinese and english for eg. Both are as different as night and day.
Mastering both languages to use both proficiently definitely takes much more effort to learn compared to mastering say english and spanish. Chinese words alone can kill even chinese ppl.
Learning those ang moh languages is somthing like teochew ppl learning hokkien. I grew up in a teochew speaking environment but i could understand hokkien when i served ns. Hence i actually learned a new dialect just like that.
