>I can’t speak to the private prison stuff, but having grown up in the 80s in the US, I can tell you that the Wikipedia article is not complete for the 80s.
>There was an enormous anti drug push at the time, culminating in 1989. It was everywhere in the culture that I experienced. Maybe a backlash to the popularity of cocaine at the time, I don’t know.
Maybe that's just biased by your memories? If you came of age in the 80s, you're obviously not going to remember all the anti-drug/tough on crime stuff that happened in the 70s. Note that just because that there weren't many developments in the 80s, doesn't mean that they weren't doing anti-drug programs in your school. It just means that the relevant policies were already enacted.
The wikipedia article for "tough on crime" also shows a similar timeline. Crime became a political issue well before the 80s.
