Why not let people have control over their own life?

Democracy allows Socialists to have control over the lives of other people.

But we do not ask people which is the best system to live under, instead we ask which party is preferred. The jury in a court is attempting to get to the truth. Elections, it is often assumed, are not so much about getting to the truth as expressing a preference, between parties. Why not have freedom instead of a big State? Why not let people make their own decisions, for their lives? Why not let them have control over their life?
