Corruption in India is rising

In terms of transparency, India gets 40%. Denmark has score of 90%; New Zealand 90%; Finland 89%; Sweden 88%; Switzerland 86%; Norway 85% and Singapore 84%. Reference.
Under BJP's Modi, India's rank has fallen from 76 to 79, among 176 countries evaluated. For all practical purposes, Demonetization has not reduced corruption. In fact, now people are paying more bribes e.g. to tax officials to reduce penalty, to bank officials to get cash, etc.

Why did Demonetization fail?
Corruption is not proportional to cash in circulation. Corruption is proportional to taxes / rules / regulations. The more taxes in a country, the more rules/regulations in country, the more the bureaucracy in a country; more is the corruption.
The ONLY way to reduce corruption in a country is to reduce taxes, rules, regulations and bureaucracy.

BJP under Modi has not taken any significant steps in this direction. In fact, after demonetization, the rules/regulations/bureaucracy have increased. Now, new taxes are being introduced on cash withdrawal. Hence corruption is going up, not down, under BJP's Modi rule.
Indian politicians are should remember that talk is cheap. Essentially BJP under Modi has failed to reduce corruption, inequality and poverty.
