The article on PPF is good.But PPF should not be touched by government any more.Fostly there should be no difference between EPF and PPF interest rates.Secondly being for old age and retirement benefits persons above age of 50 if withdrawing funds from PPF should be treated under EEE scheme only.I can't understand this logic of exempting the investnebt and interst first and then tax it when person wants to use it. PPF is welfare and social welfare scheme and thus government should niot apply same yardsticks to it and NSC. Not only interst rates should be atleast 9% but should be always EEE. Government should fund losses through Union Buidget welfare allocation.Except for public servants, there is hardlt any soial security cover for Indian citizens despite what kind of job they do. This is bad.A typical citizen say working as middle level executive in a SME not only gets much lesser salary and perks than a civil servant but also has no beenfits like opension,medical reimbursement,housing loans,public owned housing on subsidised basis. Is this country working for care of public servants only who are otherwise supposed to serve people.They are most beneficiaries of welfare schemes
