system is to be change means mainly election process. money reqd to fight election is root of corruption and this evil was started by indira... before that things was much better comparatively... in my view following to be done to fight corruption.
1. Budgetary provision for elected and second rank candidates. National Political parties should be provided election money according to their winning candidate from central budget. Similarly state elections from the state budget and parties must have to provide their spent account to get such fund. CAG should audit this fund. This is one way in the long term we can counter corruption.
2. Business house donation to political parties should be banned strictly. Put heavy penalty to both the parties if they give/take.
3. Simplification in all the laws like Income Tax, Vat, Excise, Custom. Only one tax in the form of GST as alternative to all the taxes is good move and should be made much simpler. Make simple law, which common man can understand, so no question of breaking the laws.
3. Strong and independent Lokpal bill must be framed which should made accountable to all including PM, President, CJI, MP, secretaries, and even election commissioner. Since all are Indian citizen first and so they are holding the post. So, all should be accountable. All other agencies like CBI, CVC, can be merged in Lokpal to make it more strong, powerful and independent. This will have parallel check on govt.
