I know this was likely made tongue in cheek, but it's actually something to think about.
It is not.
The US isn't as bad as Belgium, over here it is a farce, we are paying the bottom of society massive amounts of money in order to breed.
Here are some of the official numbers:
Pumping out a kid? Have € 1.144,44.
Pumped out a kid? € 166,46 goes your way, monthly
Kid old enough to go to school? Add € 20,81 - € 62,42 monthly (we have free education for low income groups)
Also add a yearly bonus for kid in school - from € 105,98 to € 3720,75 (!)
Are you unemployed and thus poor? Add € 83,23 - per child - monthly
Can you get your kid diagnosed with ADHD/Autism/..? Add between € 84,02 and € 560,10 monthly
A surprising amount of children in the lower class has ADHD (basically they didn't get a proper education and their shit behavior is blamed on it).
Each kid generates easily over 400$ / month, while education is free, food at school is free, and they wear the clothes their 6 siblings did before.
On top of that, having kids will speed up the process of getting social (free) housing, and the place you get will be better. Legally, each child should have its own bedroom, so if you pump out 4-5, you'll get a 4+ bedroom villa with at least 2 bathrooms .. for free!
Finally, having multiple children and being in a low income scale, means you literally pay no taxes. You get reductions on gas/electricity/interweb, cheaper healthcare, ...
