I am really surprised by this.  I read the memo and it did not say what Heinen said.  

But I will say this.  When I was 36 and pregnant and a litigator, I went to a meeting. All the females were young and the males my age or older.  I realized I was seeing less and less women lawyers my age. And my law class had been 53% female.  Where had they gone? 

They had dropped out.  As I eventually did.  Heinen has to know that.   She has to see the attrition rate. The VOLUNTARY attrition. 

No one forced me out. 

I am surrounded by females - lawyers and doctors -who made the same choice.  Part time or stay at home. 

We could all afford it because we married classmates or men of similar education. 

Sorry if that is not politically correct.  But it's true.  And everyone I know did it voluntarily. Often over the objection of their husbands who would have preferred the extra income.
