If I were PM, I would first of all have a composite biometric ID card for every Bonafide Citizen (after honestly determining their citizenship), which would do away with all other cards, such as ration cards, election cards, etc.
Get rid of all illegal immigrants forthwith on a non-negotiable basis.
Ensure that we are all conscious of the fact that we belong to one nation, I would have a uniform civil code for everyone. For the detractors, who feel that this would take away religious rights, I would send a clear message that religion is a private affair which should be practiced privately or in the confines of churches/mosques, temples, gurudwaras, synagogues, without loudly spilling onto streets , parks and other public areas which are not sound-proofed. If we wish to be called a civil society, civil norms, as per existing laws, should be adhered to.
Ensure all existing laws are strictly enforced by enforcement agencies, without fear or prejudice. That all agencies, especially government, security and public agencies, be brought to book and exemplary punishment given, should they be found failing in the execution of their duty, for which citizens are paying them a salary.
Have all donations to political parties be brought into the political domain and be legalised, so politicians have no excuse to hide behind and industrialists are also held responsible to one party or the other instead of being fence-sitters .
All "Bakshish" be deemed as bribes and be stopped forthwith. Salaries of security personnel be improved and their appoinments be made on the basis of merit alone.
All"quotas" be stopped , beginning from educational institutions to jobs, for gender, tribal, caste and religious quotas and merit be the sole criterion in operation. Only those who are economically unable to pay, should get free education upto STd. X and thereafter begin to work and contribute to their families and the nation.
Lasly, perhaps the time has come for us to adopt the American Presidential system of Government, where Ministers can be appointed from the opposition while forming the Cabinet,thus placing the nation's interests above partisan party, caste and political considerations. Besides, the campaigning itself for 21 months State by State would seperate the wheat from the husk quite effectively and thus free us from the snowballing effect of lard and corruption that we have inherited over the past 60 years of independence, earning us the dubious distinction of being in the five top most corrupt nations of the world! Policy makers, Politicans, Law Enforcers, Industrialist, hang your heads in shame!
