I suggest govt to come up with opt in or out cpf for those who started working:
1) u can opt out of cpf. U r on your own. Employer no need to pay u 16% (employers laughing all the way to bank) and u keep your 20%. U will not have anything in your cpf account including medisave because u never deduct money 20% for cpf. You die your own business.
2) u can opt in cpf, u get 16% from employer and 2.5% interest rate for ordinary and 4% for special account but u need to follow whatever the govt implement, this includes retirement age and minimum sum.
