Because we made too much (over minimum wage, dual income household). I was making $13k as a sales manager, my wife was making $8k as an assistant manager, and minimum wage was $3.35/hr or just under $7k/year back then. After taxes, we made about $1200/mo, and our rent was $650 for a single bedroom apartment. No car, we took the bus, barely had enough for food and utilities.
But we were considered way too over the “poverty line,” which was I think less than $6k/year then. We had been using birth control but when they say some form of birth control is 99% effective, the DO mean 1% failed. I have no regrets our son was born, because it turned out we couldn’t have kids later when we tried. And then later my wife died when he was 22, so if we had kids later, I would have been a widow with younger kids.
I feel awful he grew up poor with us until he was about 10, though.
