Tucked into the 2017 law intended to cut Americans' taxes was a program aimed at helping communities struggling with high unemployment and run-down housing. Known as "opportunity zones", supporters on both sides of the aisle say they are creating jobs and making a difference in places that might otherwise be left behind. Critics say residents in those communities actually may be harmed because wealthy investors getting tax breaks could enjoy more of a benefit than local residents. However, both supporters and critics agree that more information is needed on the actual impact of these zones.
