What's happening?

Liang Dingzi wrote about this guy who has past the age of 62 and wanted to continue to contribute to the Supplementary Retirement Scheme but were rejected by the MOF. I would think the govt that is so concerned about retirees having no savings and wanted to introduce compulsory annuity schemes would be happy that they are willing to keep more money in the CPF. Maybe Eng Hen should have a word with MOF on this. If people are willing to save more voluntarily, then there is no need to compel them to do. What's happening?
