One simple question.
Either in Singapore or Norway, you need to have loads of money to
have the good life.
Agree?
If their life in Singapore is better than Norway, then they must
have some financial advantage here that they don't have in Norway.
If you don't have much money in Singapore, there won't be any life
at all as opposed to Norway.
Anyway, if it's possible, I don't mind trading my Singapore
citizenship for a Norwegian citizenship anytime of the day.

Maybe spend afew years acquiring the Norwegian language.
I am sure many educated Singaporeans won't mind trading too.
If you ask me what values Singapore holds for me, I will tell you
zero. It's nothing more than an empty shell, the voids could most
easily be replaced by PRCs, Indians, Indonesians, Malaysians and
Filippinos anytime.
Does Singapore value her citizens?
That's for you to decide on the merits of their actions.
