She needs to be earning at similar levels to what i earn.
Many girls have dreams about life after they get married, mostly on the money earned by the husband. I am not one of those guys who could fulfill those dreams. Neither am i desperate. With both spouses earning enough, there is a freedom to take risks in life (eg: a startup, an unconventional career option ) given you don’t have a wife dependent on you. That is very understated compared to a life where a wife is just dependent on the husband.
Given today’s environment, a wife’s role would be artificially rated higher anyway, so better she actually contributes equally than not. I am fine with getting maids for all household work and if she is busier than me.
