Worked with both centre and state. I feel bribery as such is now less on the face mainly because higher offficials come down heavily on grass root corruption. However whereas there is a tendency to eliminate grass root corruption it has persisted or become more at higher official level. There are beaurocrats who feel it is their right to have a share of everything.Central offices tend to be strict with everything but there are murmurs of shady deals , contracts , kickbacks. We have eliminated monarchs but grown a new set of people the IAS/IPS/IRS/IFS who consider themselves the rulers of the land. That said there is cut throat corruption by the immigration , customs etc which of course hurts national interests.

State direct corruption is there in some departments and the bigger fish have connections that maintains them.

Dealing with organised corruption is not straight forward as it seems. A lone corrupt taking 100 rupee can easily be disciplined but as I said the organised one has a lot of backing and things will start backfiring if not careful.
