Acc to what you are saying now, people migrated because of the political landscape here, and having decided so, wanted to take out their CPF. Now that's quite different from what you said earlier - that people migrate because they want to take out their CPF. The second is an act of a confused person, the first is an act of a sensible person. The difference between what you wrote then and what you write now is called confused.
Looking back say 10-15 years ago, many Singaporeans migrated for some common reasons which I do not like to dwell with except saying because of the politcal landscape in Singapore.
CPF is the same money you can buy a house (a home is a home) to settle down your family if you migrated. Not many people has spare change to keep CPF money in Singapore and buy a house in cash when they migrated. So who is confused, you or him?
Since FTs do not contribute to CPF and some people CPF money are locked by PAP is confusing and no fair level of playing field for both sides.
