This is not complicated. Median household income in 1960 (in today's dollars) was about $58,000. Today it's about $88,000. You therefore have more inflation adjusted money available to spend on everything, including children.
The inflation adjustment includes everything: housing, education, and their proportion in the average US family's bucket, so calling out a specific item like education or housing doesn't change that data.
