Nowhere in the article is meaningfulness to worker mentioned, just statistics. Statistics by themselves have little meaning, until they are interpreted and put into context. For example .5% change in employment over the course of a year for a specific segment of the population is not meaningful without greater context. If employment for women changed by .5% over a year, but now housing is completely unaffordable, that doesn’t mean that people have increased happiness by .5% . Interpretation is needed.
