Talking about equality I think she can debate with herself on her statements 

Also its not just about being lucky or not Ofcourse that can be one of the possibilities However  there are ample of women in this world who are luckyprivileged enough to sit at home and stay with their kids And they choose to be still Working Moms This is because they were raised to be independent and are raising their kids to be the same 

They are neither running away from their kids nor neglecting them They just want them to be the best at every situation be it lucky or not

So be proud all you Working Moms You are creating a better world for you and for me and the entire world
