Xenia,
I have the skills to earn a hell of a lot of money. People with strong IT support skills can earn very nice salaries, particuarly if they do contracting and work in London.
"Well certainly some men prefer women not to be the major earner but then some men conversely get cross the whole having to support the family thing falls on them whilst their wife gets a choice about part time or full time work."
What hours people work, whether one parents stays at home is something that people have to decide in a relationship. I think that both parents have caring responsiblities as well as financial responsiblities.
In a healthy relationship a husband and wife listen to each other. As far I am concerned its private arrangement between two grown adults how they divide their labour. If a SAHM is support by her husband its none of anyone else's business. The important thing is that both people are happy. A good marriage is a symbiotic relationship.
Like Xenia, would would rather pull out my own teeth than be a SAHM. My husband and I choose to do a bit of everything.
"concentrate on your children, manage your own hours etc. "
How can you do that if you work 100 hours a week? I work flexi time, I have a reasonable amount of automony in my little job. I work to live rather than live to work.
