Real oppression has existed throughout human history. In the ancient world, slavery was commonplace. In those times, ethnicity was no protection: millions of whites were enslaved by other whites.* Later, in America and elsewhere, ethnicity became a dividing line. Africans were brutally oppressed during slavery times; after the Civil War, segregation became another form of oppression for African-Americans. True oppression of various kinds are at work in the world today.
But the ubiquitous oppression that omnimarxists perceive is pseudoppression.
pseudoppression n : a supposed social process which is depicted as an unjust exercise of power
pseudoppressor n : a member of a group falsely perceived by progressives to be oppressive
pseudoppressed n : a member of a group falsely perceived by progressives to be oppressed
What is the psychological impetus for believing in a fantasy oppression between exploiter groups and victim groups? It depends on your group membership. Pseudoppressors can do progressively-virtuous works and expiate their guilt over their social success. For instance, wealthy progressives perceive themselves as oppressors, so they attack capitalism and support wealth redistribution (usually of other people’s wealth) as a way to gain progressive virtue. A second impetus for pseudoppressors to accept the validity of omnimarxism: opposing pseudoppression can be an easy path to power. The progressive culture rewards those with public progressive virtue and the “courage” to attack pseudoppressor groups.
On the other side of the equation, the pseudoppressed also for several reasons buy into the omnimarxist viewpoint. First, they can give up responsibility for their own lives. For example, progressive non-Americans, perceiving themselves as oppressed, can claim that the deck is stacked against them and blame their failings on Americans. Second, simply put, the pseudoppressed can feed in the trough rather than toil in the field. Third, omnimarxism allows the pseudo-victim to guilt the pseudo-aggressor and therefore control the relationship in a passive-aggressive manner.
Again, true oppression has and does exist. But in modern America, most of what is purported to be oppression is a delusion or a scam.
