Union support is substantially higher among younger cohorts, and ~2 million of the 55+ cohort ages out annually, so support should skew upwards over time. Progress in this regard is a function of time.
If this logic held, we in democratic countries would only have left-wing governments. Actually, people like unions less as they age for various reasons.
That does not necessarily follow. You can’t assume the younger cohort won’t change their opinion over time.
Which just brings it to where it was in 2021, which is the highest it's been since 1965?
> Its higher than a long term average of 62% and lower than all time high of 75% following WW2 when unions were in their heyday.
Is "following WW2" January of 1957 where it was 75% or August of 1957 where it was 65%. I'm thinking there's some margin of error in those 50s numbers.
