Imagine a poor cishet white man. In Marxism, he would be among the archetypal examples of the oppressed. In Maoism... well, I am not very familiar with Maoism. But in SJW-ism, he would be considered a privileged oppressor.

When I see SJWs mentioning poverty, as far as I remember, the poverty is always framed as something that happens to women or black people or trans people etc. Like it is just another injustice that happens to people who are already disadvantaged along some of the recognized axes. Instead of being a standalone axis, a cause of disadvantage. (In other words, it is never "poor people have it bad", but it could be "women have it bad, especially poor women" etc.)

You are allowed to complain that there are too many male CEOs. You are allowed to complain that women only make <insert random number> cents for each dollar men make. But you should never compare a poor man with a rich woman (unless your point is that the poor man is still more privileged).
