If you are a Singaporean and read Mandarin.. this article from a magazine in Hong Kong would be interesting for you.
Singapore has low foreign debt..
Is our debt low because the Singapore government borrows from it's citizens.. compulsorily through CPF?
Or is our tax high because CPF (compulsory savings for working Singaporeans) is money most of us are unlikely to ever get back in our life time?
Whatever you think, this is an interesting read.
