Two-earner households obviously have a large independence over single breadwinner households in being able to 1) afford housing 2) afford to pay for education.

'Liberation' has meant that for the majority of women, if they want to raise a family without financial disadvantage, either must work or be very choosy over their husband's earning potential / wealth.

Is that really an increase in choice? Most people do not have the financial cushion to stay at home, even if that's what they really want.
