Are you serious?? You mean a court can take away a child from the birth parent/family if they don't make a certain level of income?? Or if they don't live in a nice, middle-class suburb?
Surely not.
Sure they can when it comes to 2 parties wanting custody of a child. It would be Birkhead ~Vs~ Virgie.
Remember that Birkhead was not married to Anna - which is another factor - basically it would be Birkhead & Virgie on even ground when it comes to custody of the baby since Birkhead was not married to Anna. That is when they start looking deeper into each parties life style, home life, income, etc. (even the age of the parties fighting for custody becomes a factor.)
I am not telling you I agree with this - but that is just how things play out during custody battles - everything weighs in.
