Vicky, equity is not a slogan on a cereal packet. It is sharing the domestic crap from day one regardless of the hit on your social life or career and not expecting your wife or partner to do it because she is female. When men do that as a matter of course, and men are making 50% of the domestic buying decisions, then this question will not even arise. But nope, easier to upend cereal in a supermarket aisle than years of domestic slog.
Women lose out financially and in terms of leisure time because they do much more of the domestic stuff from the year dot. Women do not have equality. Equality is not a slogan on a cereal packet.
