Question

why did people oppose the government despite the economic and social development initiatives in undertook

Answer 1

Because of unawarness in people. The opposition parties takes benefits of it and tell people that current government is not doing its work properly

Answer 2

The government (of any country) is a very large organisation. It cannot keep a direct view of initiative or operation it untertakes. various smaller bodies like state or district govt. watch these initiatives which are not as responsible as the central body is.
2 the second reason for the oppose by people can be lack of understanding and communication. many of the people do not even know that a particular initiative they want is already is in progress. However for this solution the govt. has opened various panels and acts like RTI.
3. a very common reason for this is the diversity of people. While the wants of the people vary from one person to another. The government has to do good for everyone. while some are satisfied, others do not.
