I personally dont think a woman have a right to her earnings to her husband.
However, the jews instituted that since the husband is obligated to feed, clothe and provide housing for his wife it is only fitting that he should be the beneficiary of her earnings.
It should be noted that even after the JEWS established this rule, if a woman wishes, she has the right to tell her husband, "I will support myself and I will keep my earnings."
but it is advice able to say that a wife should give her husband all she have since the Bible verify it that
"THE WIFE AND THE HUSBAND ARE ONE FLESH"
so it is a capital YES to the post above
HOPE THIS IS CLEAR
