"So the all-the-AC-all-the-time thinking of the US may be excessive,"

Unfortunately, there are many areas of the US where humidity is the real reason for running the AC so much. In places like the Mid-Atlantic states you might get a month or so in spring and fall where you mostly don't need AC or heat. Once summer actually hits, it seems rare to have a day where it's under 85F and under 70% humidity. The south is even worse.

Fun fact, air conditioning was invented for lowering humidity in warehouses, hence why it is called air conditioning and not air cooling.
