Over 50% of couples in my country have an only child. People have been trying to pin low birth rates on everything already. There are studies, there are special programs to pinpoint and fix the hindrances. Politicians are breaking their back between blaming people and implementing special programs that are supposed to raise birth rates.

To me the reason seems obvious, just by looking at the parents around me. Raising kids is not nice. It used to be common knowledge that kids are a headache. No one expected parents to actually enjoy their kids for too long. It used to be ok for strangers to yell at random kids for being loud.

Now there's this trend of people pretending that kids are nothing but rainbows. This bled into the birth rate discussion in that people seem to be pretending that they don't know that kids are annoying and why couples are not eager to have them. When there's more than one kid they will fight. This is a considerable annoyance. Small kids will ruin your health, sleep and they will scream like a dying animal for no fucking reason in the middle of the night. This is not nice. Adults want to come home to a quite house. When adults outnumber kids you can still have a nice balanced life. You can get away for a while. With multiple you will be pissed for a considerable percentage of the 20 years when they live with you.
