What Indian Economy Lacks?

Being the biggest Democratic country in the world, it's always a tough job to control anti-social activity . But we have a large population and many people are interested to join the defense system , then why we are weak in defense when compared to other countries like China,America,etc...
  Rather than investing so much money on defense, why not these  government be strict against terrorism and corruption.
Still how may fasting did Anna Hazare need to take for achieving this goal ?
  There was a saying in late 90's a cost of a vada is 50 paise and the cost of a call is Rs.5/- , but now its vice versa. Through a modern technology, we can bring down the cost price of  a phone call, why cant we bring down the vegetable and food prices. Why the inflation is up ?
  Through illegal market business is reaching upto 55,000 crores . This is a biggest loss to Indian economy... So whats the solution for all these things.

Fight Against Corruption !!!
