human oppression is a universal experience

I saw this expression in a blog recently:

... human oppression is a universal experience ...

There is a contradiction here. If everyone is oppressed, then who is doing the oppressing? Maybe we have a system of mutual oppression: I oppress you, and you oppress me in return.

But no, I have misunderstood the expression. Being an oppressor is part of the experience of human oppression. This is like saying that the rapist and victim share the experience of rape. That means the person making the quote thinks that oppressor and oppressed suffer equally. Bullshit!

Another interpretation is that some people experience oppression early in life and are able to become oppressors themselves. This is what Capitalists mean by the ladder of opportunity. Climbing it means you get to oppress more and more people.
