When the Government became oppressive?

In a democracy, it is expected that the people should decide the policies of governance.

Then why the government do exactly opposite to the public demand?

There is one reason: Corruption and the other is negligence towards the duty. If the gain is 

high, the government, say our representatives, do things against the wish of people. The voters

should became aware now and must ask about their plans before we elect them. If they 

presented different plan and activated the different one, we should have the power to recall them

from their posts. Only then they will behave responsibly.
