How sad is it that this was written in the 70's, and very little has changed?

Seriously, has much changed since publication of this? My girlfriend thinks that maybe postponed marriages have had an effect of teaching men to do more of their own housework. I think that it's more than that - more of us have grown up in environments where we're not given "boy" passes. We all have to pull our weight.

What say you?
