The city suffered from the mid-century restructuring of heavy industry and railroads, which cost widespread loss of jobs. As a number of local factories began to close because of changes in industry, the railroad and meatpacking industries also were cutting back and moving jobs out of the region. This led to a precipitous loss of working and middle-class jobs. The city's financial conditions deteriorated. Elected in 1951, Mayor Alvin Fields tried funding measures that resulted in raising the city's bonded indebtedness and the property tax rate. More businesses closed as workers left the area to seek jobs in other regions. The more established white workers had an easier time gaining jobs in other localities, and the city population became increasingly black. "Brownfields" (areas with environmental contamination by heavy industry) have made redevelopment more difficult and expensive.
