Yes, this does not work the same for women, because if a man wants to have children, he cannot have his wife be so devoted to her career that she is not willing to give that up to have children. Maybe this is not "fair" for women who want both the career AND children, but it is also not "fair" that men have to make something of themselves in order to be in the position to have a family.
That is just reality, regardless of whether you think it is fair or not.
