what you said is funny.
The rich is only 10% or so.
As you said, the rich can opt out. But they so rich, why they would
opt out ? They basically have no urgent need to tap on their CPF.
Opt in or out for them is not an issue. So, they may save the
trouble to opt out and accept opt in. Of course there is no opt out
option now.
So, unlikely more than 1% of the rich will opt out.
As you also said, the majority poorer, may like annuity like
you.
So, why you worry about them opting out?
Thus, Opt Out should be safely given as an option, by your logic.
the logic of oxford mushroom. He is the one whose views allow me to
support my logic of Opting Out. Gazelle, report to your farmer
master, he sabo your clan.
