Do you have any evidence for this assertion, or are you relying on intuition here? A cursory search yields a number of references similar to this one---https://reno.nyloffices.com/resources/articles/starting-a-fa..., which indicate that the cost of raising a child has gone up significantly, at least in the last 40 years. And many of these references do not include the cost of college, which has skyrocketed. I'm not sure what you mean by "bringing up kids the way they were brought up in the 50s and 60s." They certainly had housing in the 50s and 60s, and that single expense alone is probably enough to make today's kids more expensive.
I don’t have any intuition or stats either way but that’s a bad and biased citation.
Which is not surprising giving it’s selling something.
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.
Median housing cost in 1960 was $11,900, which was about twice the median income at the time. Today it is nearly $400K, which is over 4 times as much as the median income. Medical and education costs have similarly risen faster than inflation (and faster than wage growth). You're right that it's not that complicated, though.
I know it doesn't feel that way, but that's because of the hedonic treadmill.
Median income is exactly what it sounds like, the median income.
>The deflator used to correct incomes over the years includes housing and education.
That may be the intent, but it is clearly not working, because housing, medical, and education costs have in fact risen as a percentage of income.
On the other hand, you have the Dunedin study, where lead exposure was uncorrelated with measured socioeconomic status, which found weak links with offending overall and no significant link to violent crime.[2]
In any case, people talk about this like lead was the dominant factor in the violent crime decline, when these results don’t establish that. Even the meta-analysis leaves most of the homicide decline unexplained by lead.
