The economy eventually recovered from the low point of the winter of 1932–33, with sustained improvement until 1937, when the Recession of 1937 brought back 1934 levels of unemployment. There is a broad consensus among scholars that the New Deal policies did not lengthen and deepen the depression; only 5% of professional historians and 27% of professional economists believe it served to lengthen and deepen the Great Depression. Apart from the WPA and CCC, most New Deal spending programs, such as the PWA and AAA, operated through private firms.
