The NAACP will target private companies as part of its economic agenda, seeking reparations from corporations with historical ties to slavery and boycotting companies that refuse to participate in its annual business diversity report card … The group’s strategy will include a lobbying effort to encourage cities to enact laws requiring businesses to complete an extensive slavery study and submit it to the city before they can get a city contract. Such laws exist in Philadelphia and Chicago, which can refuse to grant contracts because of a company’s slavery ties although neither city has done this. Detroit and New Orleans are considering similar bills.
