By crude estimation, these corrupt officials constitute at least 90% of all the officers. According to standard of any civilized country they deserve rigorous life imprisonment. India is going through a state of complete anarchy. Origin of all the reasons behind the worst Indian situations is nothing but the inability to make right collective decisions by the Indian masses; corruption, injustice, corrupt leadership, corrupt judges, corrupt bureaucrats, etc. all are the offspring of this.

From small time clerks to the high profile politicians, commissioners, police inspectors, traffic police, stock exchange brokers, military establishments, recruiters, sportsmen, judiciary and most of the government employees, corruption is seen and felt in every transaction from bottom of the chain till the top.

The Prez and the PM both are known to be really clean. If they start a campaign, I am sure the Media will join enthusiastically. That should indeed make a powerful beginning. But how far even that can go would depend on the Most powerful person ( you know who) - dependence on a dozen political parties for survival of the Govt. may prove the villain.
We are doomed not because of the level and spread of corruption so much, as due to the fact that values have changed in the society to such an extent that the corrupt are no longer either condemned or even shunned.

In the recent times the private Indian companies captured the top spot in encouraging corruption when dealing with international clients in order to grab lucrative contracts.

Why are the corrupt susceptible to corruption ?

The low salaries of people made them susceptible, bringing with it more inefficiencies and the easy way of making money with less or no accountability. The crime of corruption is easily forgotten , the law offers easy way back into the mainstream and acceptance by the society. In addition to that it is the lure of luxury, personal status enhancement and the false sense of elitism that makes the corrupt vulnerable to illegal and unethical means of acquiring wealth.

The cultural connection and other reasons.

Indian society still has a cultural setup of having the "man of the house" to work for a living, while the wife usually deals with the household work,and this puts a pressure on the man to make the living more luxurious. The routine jobs are usually for life-long, with the support of a union there is a lesser fear of losing the job and there is the pressure of dealing with rising prices of commodities and sponsoring future education of children. The society ,the social upbringing, the culture and a general greed also plays a critical role in influencing a timid mind. The lack of instincts and to avoid the time consuming bureaucratically setup of the organization, the corruption may be a easy way out for people who bribe to make things happen.
