This term tends to be nebulous when I encounter it in online writing.

Often when the word "millennial" is evoked its definition forgets the lived experiences of gender and/or race.

Usually the word "millennial" soaks up the biases and assumptions the author has towards the socio-economic situations of white people born in Canada or the USA between certain years (1981 to 1996 in this case). Let's us not forget that socio-economic potential is not one-size-fits-all.

The cover image of this article is of a white male holding a child which I suspect is to garner the attention of white male readers to which further suggests that when the author is discussing "millennials", the author talking about white males.

"Millennials" tend to have their housing, technological, financial, and global climate potentialities spoken about in bleak, unforgiving terms. So what you end up with is "Millennials" or "white males born between 1981 to 1996" don't have it as good like the generations before them or, in other words, "white male privilege" just ain't what it used to be.
