During Reconstruction, many white Southerners viewed the influx of Northerners, often referred to as "carpetbaggers," as primarily motivated by the goal of exploiting the South's post-war misfortunes for financial gain. This perspective largely stemmed from a belief that these individuals were seeking to profit from the South's economic struggles and the political instability following the Civil War. Therefore, the correct answer would be:
to get rich from the South’s misfortunes.
This perception was common among many white Southerners who resented the presence of Northerners and believed they were there to take advantage of them rather than to genuinely help rebuild the South.
