Well, "US pay transparency laws result in worker discontent," is just not what one should imply from a causal stand point.

"US pay transparency laws result in workers realizing that their employers are trying to underpay them and this results in workers being discontent," is the truth. This is the whole point of transparency, which I assume is what you are getting at. The transparency doesn't share any of the blame however, so the wording of the title is unfair.

Sunlight is the greatest disinfectant.
