Also, we raised an entire generation of Americans on bottles (75% of children born in 1971 were never breastfed, even in the hospital) and everyone turned it fine.
"Turned out fine" is highly subjective. The peak violence rates in the US happened when that cohort was 22; right around the age at which people commit the most violent crimes. So at least on that one metric, that cohort was probably among the worst ever (I'm not claiming a relationship to breastfeeding, of course).
Breastfeeding declined dramatically from 1910 to 1945 (and stayed below 30% from 1945-1970s). While crime went up from 1965+, it also went steadily down from 1935-1960.
