I enjoyed this article but the assertion that Work Simplification was the direct cause of high levels of trust in government in the decades after WWII strains credulity. I would have expected some mention of the twin crises of the Depression and World War II; the low levels of economic inequality in the postwar years; the oppression of large swathes of society (who presumably weren't surveyed); or the increase in political polarization since the 1970s - factors which intuitively appear more relevant. The article would be much improved if it attempted to explain why Work Simplification made such a big difference.
