sure- with working couples there has to be parity in how much work they do at home, but lets be clear, parity overall..if one person works 60-70 hours and other works 40, then the one working 40 should not expect the other one to divide the house work 50-50.
Its a partnership, and as soon as people understand the principle of parity the better off they will be.
I do have to point out one thing, there are other duties that mostly men handle that they handle with work too, yardwork, snow shoveling, fixing this that or the other etc etc, so to assume that they do nothing aside from work is not fair either. its different stuff, and as long as couples coopaerate rather than draw battle lines, its all cool.
