Give money to each woman to have tubes tied and man to have vasectomy, your saying that won't work get real, they would jump at the chance for free money and the women would not have to go through pregnancies and babies they couldn't afford to feed. Seriously you need a licence to drive a car, but not one to have babies thats absolutely crazy, whoever made having as much babies as you wanted  a human right,regardless of means to care for them should be jailed. No one ever thinks about the childs wishes not to be born into poverty, abuse, starvation.
