It is true that there are not as many women in technology as men.  I believe you make some valid arguments on why this may be true.

However, being a man let me give you my perspective.  Not every man in the technology field is here because he loves his job.  I am in technology because it provides for my family.  I like my Senior DBA Position good enough, but there are other jobs in other fields, I would enjoy more.  However, they would not provide for my family as well.

I try to keep my life in balance.  My job is my 5^th priority in life.  My priorities are in this order: God, Family, Myself, Career path, Job.  For me, I stand on the promise of the Bible, “Seek ye first the Kingdom of God and His righteousness and all these things shall be added unto you”.  This teaches me, that if I place God first in my life, He will  bring  balance to my life.  In my experience, He has done just that.  God moved me from a job, where I was working much overtime and had an inflexable schedule  to a postion where I am a Senior Database Analyst with a good salary that works 7 am-3:30 pm, with no overtime.  With these hours, I am able to devote time to God, be with my family, and pursue other interests.

In my opinion, if someone gets out of the technology field, because of overbearing demands, God bless them.  There are more important things in life than a fast past technology career.
