A new federal tax incentive was designed to boost low-income communities, but will it actually help those living there? In 2017, President Trump signed the biggest overhaul to the U.S. tax code in 30 years. While corporate tax reductions may have received the most attention, the bill also included a tax incentive designed to help low-income communities. More than 8,000 census tracts have been designated as "opportunity zones," where investors can receive a tax break if they put money inside of them. It's a free-market approach that, according to its supporters, will spur investment in these distressed areas. But critics say it may not do much for the very residents it's designed to help. Hari Sreenivasan reports from Arizona, where some of the first projects to take advantage of the zones are now underway.
