Army service is the same except 4 (consequences for bad behaviour), and up until 40 years ago or so, was also the norm for a non-trivial percentage of the western population; furthermore, the "no consequences for bad behaviour" is also relatively new - the greatest generation, boomers, and the one following boomers (and their equivalents in other countries) still endured physical punishment.

So, up until not-so-many-decades-ago, your statement was incorrect. It is correct now, and indeed the schooling system has not caught up, but it is doing so slowly - e.g. the Finnish led, and others are following, in abolishing the "forced labor" homework requirement.
