I do think housing costs are at the core, and part of that was more women coming into work and earning enough to make a significant contribution to family incomes.
Pressure was brought on building societies to take a second income into account when granting mortgages. If lots more people can borrow more then it puts pressure on the housing market and that drives prices up, so gradually a second income becomes essential if you want to be able to buy a house, which in turn means women have to stay in work when they would rather not.
shelflife Parents choice , they decide what is right for their family. Staying at home with children is a personal choice. This is a lovely idea but unfortunately untrue. Most women have to go back to work because they are earning half the family income and without it, they will not be able to afford the rent or mortgage payment. They then have all the problems of child care.
It is always the problem, as we seek a juster and fairer society women threw off their chains and took their place in society as equals, with all the freedom to get education, better paid work and lifetime careers. We didn't really think about the downside. Or rather we could not foresee the downsides, because we could only predicate them on the basis of our existing experience.
One of those downsides is that women with children have to work because their income is essential to keeping a roof over the family and bread on their plates.
The vast majority of mothers now have to put their children in day care in order to earn a living. The exact reverse of the days when women had to stay at home to look after children. At the end of the day it is the women (and children) that are the losers.
