Federal Reserve Chairman Jerome Powell traveled Tuesday to a historically black university in the Mississippi Delta to deliver a message that the nation’s prosperity has not been felt in many such areas around the country.Powell said that many rural areas had been left out and needed special support, such as access to affordable credit to start small businesses and high-quality education to train workers. In his comments, Powell did not address the future course of interest rates or the Fed’s decision last month to announce that it planned to be “patient” in its future interest rate hikes. That decision triggered a big stock market rally from investors worried that the Fed was in danger of pushing rates up so much it could bring on a recession.Addressing the current economy, Powell said that economic output remained solid and he did not feel the possibility of a recession “is at all elevated.” He noted that unemployment is currently near a 50-year low.“We know that prosperity has not been felt as much in some areas, including many rural places,” Powell said in an address to a conference on economic development at Mississippi Valley State University. “Poverty remains a challenge in many rural communities.”He noted that 70 percent of the 473 counties in the United States designated as having persistent levels of poverty were in rural areas. Among the problems being faced in the Mississippi Delta, Powell said, were the loss of jobs in agriculture and low-skilled manufacturing because of automation and outsourcing of manufacturing jobs.
