Aggregate political will is a feature of democracy. The fact that any single person on his/her own wish cannot make a big impact change is how a democracy is designed to work. For a democracy to work people need to take active part in the political process including things like consensus building. Changes start at grassroot level and is usually localised. You would have more impact at your constituency level than at state or national level. But the fact is that significant number of people do not even fulfill their most basic duty of voting.
