Gender Bias And Man Ego

When a married man turned from dual household income into single household income; his wife calls herself either housewife or homemaker. But, when a married woman turned from dual household income into single household income; her husband doesn't calls himself either househusband or homemaker. He called himself early retiree or F.I.R.E!


Modern married women; many of them are earning much higher income than their spouse. Who should be the homemaker when one of them decide to retire early?
