I bring stats, and sources to refute baseless statements, and I get down voted. Any ideology that requires false statistics will fail.

In single income families, the income is shared, the household or domestic partners work in not uncompensated. And as to expenditures, the domestic partner, primarily the female childrearer is in charge of a huge percentage of that income, for everything from vehicle purchases, vacations, furniture, clothes, etc.

If I'm wrong, show proof.
