This comment bears very little resemblance to the reality of working people, at least in the U.S.
Nearly half of working mothers are their family’s sole or primary earners. Another quarter of working mothers are co-earners that contribute to 25–49% of their family’s earnings. The majority two-parent households cannot afford to not have both parents working. And the number of households where the wife is the primary earner is growing every year.
Your notions that women are working for fun, or are somehow less serious about their occupational motivation is deliriously antiquated and insulting to working women.
Women seek professional success and financial success for just as many of varied reasons as men do. Some because they have families to support, some because they seek financial success and many because they have entrepreneurial ambitions.
