Agree with you that SG may in need of cash.
That's why we need a new govt to check what's left in the coffers
The moment a new govt comes in, they will find out the truth. Now what the new govt does is crucial.
if they reveal the truth, Singapore will collapse within a month. If they are smart they will not say anything and carry on. Any move to ask for more straight cash like issuing govt bonds will show weakness and cause a similar loss of confidence.
So you cannot win. Either you get a new govt stupid enough to reveal Singapore is broke and cause disaster or more of the same from PAP-style governance.
