For perspective my apartment costs ~$17,000 per year so having a child is the equivalent of renting a second home. That's a cheap apartment too. Just to break even you'd have to make $34k/yr. but you won't live. You still have to factor in bills, insurance, medical expenses for yourself, travel costs, car insurance, food and basic living supplies. The cost is staggering because there's a lot of unexpected expenses like broken arms, various flus, vaccinations and mental health services. Unless you want to raise your kids the same way niggers raise theirs you're going to be spending much more than $17k/yr.
Lastly there's a disparity between the cost of living and wages.
