The job of a government is necessarily long term.  It is right that once the people have given it a mandate it should be able to carry out legislation with long term aims. Often good legislation is unpopular at first, but effective and popular in the long run. Such legislation would never survive a referendum. It is only fair that the government is given a chance to see if its legislation does indeed work. The people can then vote the government out of office if it fails.  Similarly, it is government’s job to lead and not to follow, especially on social legislation. For example, the US civil rights movement in the 1960s, and the equal marriage movement currently, might not command majority support from the public as a whole; [1] in order to advance equal rights, responsible government has to get out in front of public opinion, and make the argument for policies which are not yet popular enough to be passed in a referendum.  This approach is justified because parliamentarians are representatives not delegates (as famously pointed out by Burke to the electors of Bristol in 1776) [2] and can do what they think is best for the people even if that does not meet the people’s wishes.
