There is strength in numbers, we need to mutiply our population by 3x. This means each couple needs to pump out at least 6 kids. And because we do have uninterested guys, let's just say each female needs to pump out 6 kids, it doesn't matter if a dude banged 10 women and reproduced 60 of his offspring. Don't worry about expenses, that's what Welfare is for. Send your 6 kids to college and wha-la! A bright future for our people.
