Or you can view it as the sacrifice of the private sphere (family, children, home and hearth) at the altar of the economic sphere.
I suppose I view it as a bit of both. I certainly don't like the idea of people being forced into marriage. But I'm also skeptical of the rejection of marriage. I don't think a career can replace a family. The reason I have a career is so I can have a family.
A lot of people in their 20s seem to think that their dayjob is actively involved with "making the world a better place" and will lead to fulfillment. I think "brainwashing" is a fairly accurate word to describe that mentality.
