The most common and yet most dangerous aspect of our great democracy is the tendency to view electoral success as carte blanche to enact one's wishes. Liberals, conservatives and socialists alike take the opportunity of a majority in the House to pursue their agenda and to reward their people irrespective not just of the wishes of the losers but also of their interests and liberties.
So with a Conservative victory comes tax breaks for the wealthy and benefits for landed interests, while Liberals and socialists in their turn "Soak the rich", diverting people's hard earned wealth to their pet projects. Politicians cite their democratic mandate to attack those whom they view as their political opponents (the "evil rich", the "lazy poor"); in the 1970s, Denis Healey wanted to "make the pips squeak" with high taxation.This is not what liberalism is about.
On the contrary, this is the very reason why liberals are concerned with the power of government. Government may be chosen by the majority but it still must represent the whole of society. Otherwise, we have the elected totalitarianism of Venezuela or the tribal politics of Kenya, where whoever wins rewards their allies and kinsmen at the expense of the rest.
Individuals, no matter how high-minded they might be, cannot be trusted to rule in a neutral and even-handed manner. We are all fallible; we are all biased. Thus, liberals must rule in a manner that recognises their own fallibilities and ensures that government does not serve any particular portion of the population, no matter how large and how needy they may be. Government should not serve the deserving. Government should limit itself to providing the basic framework within which individuals may thrive.
Democracy allows us to choose who will rule us and what the rules will be, but it does not excuse governments turning upon or exploiting the losers.
