The fact that political ideologies are tangible realities is not a proof of their vitally necessary character. The bubonic plague was an extraordinarily powerful social reality, but no one would have regarded it as vitally necessary.
The genius of our ruling class is that it has kept a majority of the people from ever questioning the inequity of a system where most people drudge along, paying heavy taxes for which they get nothing in return.
The government, which was designed for the people, has got into the hands of the bosses and their employers, the special interests. An invisible empire has been set up above the forms of democracy.
The way people in democracies think of the government as something different from themselves is a real handicap. And, of course, sometimes the government confirms their opinion.
