I believe the US doesn't have much political will to reign in her national debt.Who knows?
Actually, my view is that USD has been under-valued for quite long and it may be time to go back up against SGD etc!
In fact, my opinion is that SGD is currently over-valued given the poor stagnant Singapore economy as of now.
The only option available is for her to thrash the USD so that servicing her debt is less agonizing.
