The three main complaints against the CPF for the low balance in our CPF account at age 55 can be summarised as below:
(1) Low annual returns at 2.5 - 4%. We all know the power of compound interest.
(2) High MS making withdrawal at age 55 difficult
(3) Low or little balance in CPF because funds had been channelled to pay for high HDB mortgages
The govt can solve (1) if they want to because GIC and TH reportedly are enjoying double digit returns then surely there is little problem in paying CPF account holders better returns.
As for (2) it is not really a major issue. The full sum may not be returned at 55 (after all it may still be a good idea to lock up a small portion in CPF for old age) but the MS figure can be adjusted to say by reducing it by two-thirds or half.
Now (3) is a massive problem for the govt. They can't reduce HDB prices back to for example levels in the late 1980s where a new 5-Rm HDB cost only $120K. For those of us who purchased HDB flats from 1990s onwards will not likely support this initiative.
So the CPF issue is a big problem which will not go away easily representing the greatest challenge facing the government for years to come.
