“Capitalism is an exploitative system, as Marx has argued so cogently, and as anyone who studies the inequalities within and between the countries of the world today must see. It is therefore a priori likely that its ideology conceals realities that if known would make the exploited militant.”

Source: What is Property? (1840), Ch. V: "Psychological Explanation of the Idea of Justice and Injustice, and the Determination of the Principle of Government and of Right," Part 2: Characteristics of Communism and of Property
Context: Communism is inequality, but not as property is. Property is the exploitation of the weak by the strong. Communism is the exploitation of the strong by the weak. In property, inequality of conditions is the result of force, under whatever name it be disguised: physical and mental force; force of events, chance, fortune; force of accumulated property, &c. In communism, inequality springs from placing mediocrity on a level with excellence. This damaging equation is repellent to the conscience, and causes merit to complain; for, although it may be the duty of the strong to aid the weak, they prefer to do it out of generosity, — they never will endure a comparison. Give them equal opportunities of labor, and equal wages, but never allow their jealousy to be awakened by mutual suspicion of unfaithfulness in the performance of the common task.
Communism is oppression and slavery. Man is very willing to obey the law of duty, serve his country, and oblige his friends; but he wishes to labor when he pleases, where he pleases, and as much as he pleases. He wishes to dispose of his own time, to be governed only by necessity, to choose his friendships, his recreation, and his discipline; to act from judgment, not by command; to sacrifice himself through selfishness, not through servile obligation. Communism is essentially opposed to the free exercise of our faculties, to our noblest desires, to our deepest feelings. Any plan which could be devised for reconciling it with the demands of the individual reason and will would end only in changing the thing while preserving the name. Now, if we are honest truth-seekers, we shall avoid disputes about words.
Thus, communism violates the sovereignty of the conscience, and equality: the first, by restricting spontaneity of mind and heart, and freedom of thought and action; the second, by placing labor and laziness, skill and stupidity, and even vice and virtue on an equality in point of comfort. For the rest, if property is impossible on account of the desire to accumulate, communism would soon become so through the desire to shirk.

"Ghosts, Fantasies, and Hope," Dissent (Fall 2005)
Context: Today, anxiety is a first principle of social life, and the right knows how to exploit it. Capital foments the insecurity that impels people to submit to its demands. And yet there are more Americans than ever before who have tasted certain kinds of social freedoms and, whether they admit it or not, don’t want to give them up or deny them to others. From Bill Clinton’s impeachment to the Terri Schiavo case, the public has resisted the right wing’s efforts to close the deal on the culture. Not coincidentally, the cultural debates, however attenuated, still conjure the ghosts of utopia by raising issues of personal autonomy, power, and the right to enjoy rather than slog through life. In telling contrast, the contemporary left has not posed class questions in these terms; on the contrary, it has ceded the language of freedom and pleasure, "opportunity" and "ownership," to the libertarian right.
