To be blunt, if you love your kids you don't feed them formula.

Americans don't love their kids, so it is unsurprising that a formula shortage is a big deal. 

Formula tastes terrible and it's bad for you. Who deliberately feeds this to babies? People who hate babies. 

See also: cheerios. It has a long shelf-life because even the bacteria don't want to eat it; it's not fit for microbe consumption, let alone human consumption.

The fact Americans don't love their kids is exactly why they have to firmly signal, especially online, about how much they love their kids. This is why they go full [please somebody think of the children].

Same way every American who has ever looked twice at a 16-year-old has to go ballistic at any mention of jailbait. "Only a monster would be attracted to a girl without checking her driver's license first. I am of course a healthy male who is only interested in things the government has first given me permission to be interested in." Biology is bureaucracy, right? Animals in the wild find a mate without having to fill out form c-16; amazing, isn't it? A wonder of nature; how do they do it?

The fact [think of the children] initiatives immediately die to Conquest #3 is a reinforcing dynamic. Cause more pain to children while forcing everyone to agree that you care for them more? What's not to love?

"Maybe they don't know it's bad and bad for you." Did they check? Do they care so little about their kids they don't even bother to look? This is not rocket surgery.

Americans largely hate their pets too, by the way. I see them obviously causing pain to their pets more often than not. "See, he likes it!" He obviously doesn't. Then I look it up and guess what it's a known form of abuse.
I expect they get pets so they have something to legally torment, and they get mad at you for being mean to their pets half because they're terrified you'll notice they enjoy seeing you be mean to them, and half because they see you satisfying your sadism without paying for dog food. 

They rack up huge vet bills precisely because the animal hates the vet so much. Seeing the animal limp around and whine in pain makes them feel all fuzzy inside, which is why euthanasia is supposed to be bad. A few get confused and think the animal will really hate getting killed, but they regret it later because they can't torment it anymore. 

When you tell an American parent that cheerios are ruining their child's health, they don't get mad because you're questioning their parenting skills and need to mind your own business. They're not mad because parenting that badly obviously demonstrates they're a bad person and deserve to feel bad, and this is intolerable. "Hey, consider feeding your kid human food instead of cardboard." "Delete yourself." Since when are Americans meddling-negative? They get mad because they like giving their kid metabolic syndrome by feeding them industrial waste and you're making them feel a responsibility to stop.

I do say outlawing marriage is a primary driver of low birth rates.

However, there is a more important one: Americans hate kids. If your intuition complains about this, likely that's because it's normal to hate other people's kids. Nothing is more annoying than unrelated children.
Hating your own kids may be normal in the sense of being accordance with local norms, but it is very far from healthy.
On the plus side USG wants you to hate your own kids, so doing so is very Obedient and Conformist. Don't worry, Big Sister loves you. 

 

You can tell for certain because American parents do jack when there's a genuine threat to their kids. Their perceptions don't lead to action. They won't let them kids outside unsupervised due to the 0.0001% chance of being kidnapped by a stranger. Or - no joke, saw this in person - won't let them outside in the rain because they might get hit by lightning. (Instead, going out in the rain is an excuse to give the kid a healthy spanking. For their own good, naturally.) Then a school shooting happens and they won't even give them the day off school, never mind link school and danger. 

They will credulously repeat the ""statistic"" about 1 in 4 co-eds getting brutally ambush-raped by strangers, but never for a moment consider, you know, not sending their daughter to college. "Yes it's entirely credible that Jackie Coakley was ground into broken glass by a train run on her, but don't you dare drop out, young lady!" 

American parents obsess about car safety seats and motorcycles and then deliberately live in NYC. Americans are, of course, extra xenophobic and the "good schools" thing is a great excuse to live far away from Bantu-Americans. The kid's experience at school is irrelevant unless it can be used to change the parent's environment.

The American government lies all the time because the American people are massive liars. Demand => supply. 

There is a small minority of exceptions. Some Utah families have like 9 kids, because, "The first one was great! Let's do it again!" The "homeschooling" pull-your-kids-out-of-school reaction is indeed growing. However, slowly. Significantly less than 5% of all students are outside the Prussian system.
Prima facie, no more than 5% of American parents feel non-sadism toward their own kids. 

This is why population decline is wonderful. It will automatically stop once the 95% of parenting-negative parents gracefully exit the gene pool. Viva the pill. Viva abortion. All hail high cost of living. Outlaw marriage harder, daddy.

P.S. Ironically, stuff like cheerios kind of doesn't have a long shelf-life. They have to pack it in Communist plastic and fill it with Communist "preservatives" because otherwise it goes stale if you look at it funny. It's barely platable even at peak condition, but soon reverts to its natural "yeah, don't eat this" state. The term "preservative" refers to to sugar, vinegar, alcohol, and salt. The package-list term is a euphemism for [pesticide]. Hey, hot tip: don't deliberately add pesticides to your food, especially not broad-spectrum pesticides.
