Since he is explicitly comparing 2026 to 1926 I think his statement holds up.
Meh, seems he's using arbitrary metrics to make arbitrary claims (which is fine). But to just state that "Life is so much better in 2026 than in 1926 for Americans" is obviously a pretty nebulous statement. It's like saying "Beaches in 2026 are so much better than beaches in 1926". Sure you could cherry-pick some metrics to make the case, and someone else could cherry-pick metrics to make the opposite case. Sort've a "talking just to hear yourself talk" kind've thing.
That's how good propaganda reads. You have to be both subtle and partially true.
