Our civilization is locked in the grip of an ideology - corporatism. An ideology that denies and undermines the legitimacy of individuals as the citizen in a democracy. The particular imbalance of this ideology leads to a worship of self-interest and a denial of the public good. The practical effects on the individual are passivity and conformism in the areas that matter, and non-conformism in the areas that don't
The acceptance of corporatism causes us to deny and undermine the legitimacy of the individual as citizen in a democracy. The result of such a denial is a growing imbalance which leads to our adoration of self-interest and our denial of the public good.
The best defence [for a democracy, for the public good] is aggressiveness, the aggressiveness of the involved citizen. We need to reassert that slow, time-consuming, inefficient, boring process that requires our involvement; it is called 'being a citizen.' The public good is not something that you can see. It is not static. It is a process. It is the process by which democratic civilizations build themselves.
If allowed to run free of the social system, capitalism will attempt to corrupt and undermine democracy, which is after all not a natural state.
In general, democracy and individualism have advanced in spite of and often against specific economic interest. Both democracy and individualism have been based upon financial sacrifice, not gain. Even in Athens, a large part of the 7,000 citizens who participated regularly in assemblies were farmers who had to give up several days' work to go into town to talk and listen.
