Perhaps people can benefit from something in their capacity as a consumer while it being a downside in their capacity as an employee, and then on net as a person either benefit from or experience a detriment from the change, depending on which of the two was larger? Like, suppose someone is selling some good and they get paid on commission, as like, some proportion of the purchase cost. If the price of goods of that sort go down (maybe one of the materials needed to manufacture it became more abundant?), then they would receive less income, but also not have to pay as much for different similar goods, and whether they are overall better or worse off would depend on the details.
